Is there a way to be able to find out the external IP when the MT is behind a modem and set a noip.com name, without involving entering your account details on the Modem?
When you don’t have any access to the ISP modem and you just connect the MT on the modem (no firewall rules present on MT) is it possible to have the MT “tell” you what your external IP is ?
Basically doing what a modem does at the DDNS section to have the MT do it .
There is a built in DDNS under IP>Cloud.
If you have an update client running on a device in your network, you can enter your DDNS in IP>Firewall>Address List and it will resolve it to your IP.
Thank you 2frogs, no unfortunately there will be no other device update client running on the network …just a modem (to which I have no access) and the MT.
I was also under the impression that the DNS name in ip/cloud is not accessible when behind a NAT modem (and needs port forwarding) or are you saying that this MT dns name will me sufficient to enter it on the remote side MT and through this discovery be able to create a successful link?
Looking for ways for each device MT (A) and MT (B) to know each other’s Internet address so an L2TP/Ipsec link can be established …
If you have access to the MT router, enable ddns and look at IP Cloud it should tell you your public IP.
You will have to have port forwarding available on at least one of the modems (No IP is just another DDNS services) or you will have to connect both to third device that has a public IP or the ability to forward ports. There is no magical way of connecting from one network to another directly without port forwarding when you are in a double NAT network (external IP without access or DMZ on modem and not MT.)
Indeed true …
Here is what I did and it works, the (MT) DDNS is operating as expected to update the IP, I set it up to update every 5 minutes …now to access from winbox a MT through “that name” indeed you need some changes/access to the modem . But! If you only need to be informed of the address so you can enter it to establish a connection (a link between the 2) it works without doing anything on the modem …
Then if you have remote access to 1 location (that obviously is Winbox capable or in any other way) you can access the other MT through that location (through that cloud name) …
As others have written: you don’t need any special measures to learn the public address behind which your router is NATed, but knowing that address is not sufficient to make an L2TP server listening at your router accessible from the internet.
So one way to establish a VPN between two routers is to establish a VPN tunnel from both to a third router on a public IP.
Another way is to use an IKEv2 IPsec site-to-site tunnel where both routers act as initiators, but it is only possible if the NAT devices between each of your two routers and the internet keep the source UDP port unchanged whenever possible. See more here.
I see…good to know , thank you!
Would you say that in transport mode if I have access to one site (Server side) but don’t have access to the other side, would I be able to establish a link between the 2, by entering the static address (to call/connect to) on the client side?
E.g. if the the DDNS of the server is Server.ddns.net and the client’s name is 123456789.sn.mynetname.net
In the L2TP/IPsec scenario I see the requirement in Interface/L2TP-out-1/Dial out/Connect to : , and in IP/IPsec/peers, to enter the DDNS name or address. By entering a name there respectively for each site, wouldn’t that suffice to establish a link ? Assuming all the rest configurations are done on both…
In a typical case, there may be multiple hosts with private IP (LAN devices) connected to the internet via a single device with a public IP (the WAN router).
If the first ever packet of a new connection comes from the LAN device for a destination accessible via the WAN interface, the WAN router replaces the source address of such packet before forwarding it to the destination, and for some time, it remembers its original source address, the new source address it has assigned to it, the destination addresses, IP protocol, and ports where applicable. So if a response packet arrives later on, it matches to all these values (with source and destination addresses and ports swapped of course), and the WAN router thus knows where to forward it. This process is called connection tracking, and Network Address Translation (NAT) is an optional part of its operation (connection tracking is used for other purposes as well). Since the five-tuple of (public local IP, public local port, remote IP, remote port, IP protocol) must be unique for each tracked connection, the NAT must sometimes assign a different public local port to a connection, if several LAN devices initiate a connection to the same remote IP and remote port from the same local port via the same public IP. Some devices assign random local ports to connections even if there is no such conflict, assuming it provides better security.
But if the first ever packet of some new connection arrives to the public IP of the WAN router, that router doesn’t know automatically whether to process it as a packet for itself or forward it to some of the LAN devices, and if so, to which one in particular, because such packet doesn’t match to any connection already tracked. So you must add a static rule on the WAN router to tell it to which LAN IP to forward the packet to. Such static rules match on the same packet header fields used to identify a tracked connection, as listed above. This is commonly called “port forwarding”; to be able to add such rules, you must be an administrator of the WAN router, or have a possibility to ask the administrator to do that for you.
Even if you’ve possibly got just a single LAN device behind the WAN router, you still have to configure the WAN router to forward the received initial packets to that LAN device’s private address. If you don’t do that, the WAN router itself attempts to process the contents of such initial packet, and if it cannot do that, it drops it.
The L2TP clearly defines the roles of a client and a server. Two clients cannot connect to each other, nor can two servers. The server only listens for incoming connection requests from the client, and only sends packet back to the client if an initial request from the client has arrived. So without port forwarding on the WAN router as explained above, the L2TP server will never receive the initial request from any client.
IPsec endpoints, on the contrary, are called “peers” to express their equality; both can send the initial request for a connection and both can respond to it. This feature would normally be useless when the IPsec is used to secure L2TP, so when the IPsec configuration at the L2TP server side is created dynamically, the peer is set to be “passive”, i.e. to only expect incoming initial requests but not to send its own ones.
An IPsec peer normally uses the same port to send its own requests from and to expect the requests from the other peer at. It means that if the IPsec peer is a LAN device, and if the WAN router doesn’t substitute the source port in the initial IPsec packet sent by the LAN device, if each peers sends its initial request towards the other ones’ address and port, its WAN router will handle the other one’s initial packet as a response to the initial request sent by the local one, and deliver it.
So to make that work, you have to confugure IPsec manually, according to the post I’ve linked earlier. Whether you then use L2TP or other type of tunnel, or instead use bare IPsec with policy matching, is another question we can come back to later once you confirm the basics do work.
Thank you Sindy for the time spent and the input offered!
So how about this (based on) : “…Since the five-tuple of (public local IP, public local port, remote IP, remote port, IP protocol) must be unique for each tracked connection…”
Assuming that you have 2 clients connecting to a server over L2TP/Ipsec with the following characteristics:
Client (A) ISP address 200.200.200.1 => LAN address: 192.168.1.1
Client (B) ISP address 300.300.300.1 => LAN address: 192.168.1.1
In theory what I understand is that because the passwords, different DDNS, different passwords and the following settings:
PPP/Secrets : (Local address + remote address + routes) will be different, e.g. for Client (A): Local address: 192.168.100.1 / Remote address = 192.168.100.2 / Routes = 192.168.1.1 192.168.100.2
And respectively :
for client (B) ): Local address: 192.168.110.1 / Remote address = 192.168.110.2 / Routes = 192.168.1.1 192.168.110.2
How can you connect (e.g. from Winbox) when in Server’s location, to either clients? There will be unique characteristics for each connection, but each client’s LAN (and IP) will be the same (192.168.1.1)
Do you attempt to connect through the 192.168.100.2 for Client (A) and 192.168.110.2 for (B)?
I ask this because I may have in the future many clients to that server with a LAN of 192.168.1.x without being able to do anything about that.
As per you previous mentioned post, I understand bullets 1 and 2, 3-4-5 confuses me a little (but let me work with it and I will get back you) .
I have full access on Server MT and that ISP’s modem, but not any access on the modem of the client’s side. I can configure at my location the MT that will go behind the client’s side and ship it, but then will have no physical access to it. That’s why I am looking of ways to create a successful L2TP/Ipsec between the two without involving port forwarding and to be able to reach the client MT from (WinBox) when at server’s side (assuming there is a successful link between the two.
Also I don’t know if it is ROS 6.48.1 or me, but establishing links between locations L2TP/IPSEC has proven “difficult”…In three occasions involving 1 server and three clients: client (A) established the connection relatively easy (had to restart both routers), client (B) gave me trouble on the server’s side not getting a source address (it said @ IP/IPsec/Policies Src. Address: 0.0.0.0) it took several router restarts, disabling peers and identities, re-enabling them etc. and in the end the link was established.
With client (C) the link refuses to establish no matter what! In the beginning it showed the same behavior as client (B), then I gave up after sever retries and efforts and disabled all settings on both sides…about an hour later I went back and re-enabled the related settings on both sides and the Server side had an IP address (instead of showing 0.0.0.0), now it shows an active connection (in Active peers) but don’t see any installed SA’s ! Logs say “no proposal chosen” !!! Well, I have chosen it and settings are the same on both sides …I also disabled DPD to check but didn’t do anything…
P.S. In client (B) case where the link is successful, I cannot connect to the server via DDNS (WinBox) e.g. DDNSserver.ddns.net:1234 , If I turn my phone’s 4G I can connect to it via DDNS…
Any ideas ?
First, even a whole elephant can be eaten, but you have to chop it into small enough pieces.
So mixing together the issues of overlapping internal addresses of VPN clients with the issues of establishing tunnels between devices NATed behind dynamically changing public IPs will only create a mess.
Regarding establishing the tunnels: the suggestion I gave only makes sense where you need to establish a tunnel between two low-budget endpoints with no public IP at all, i.e. getting CGNAT WAN addresses from the ISPs.
If you talk about “many clients”, such a solution is still applicable but may be even more complex to maintain, and given the number of clients, the per-client share of the price of hosting a virtual machine in one of the public housings should be negligible.
Regarding many clients using the same subnets internally, the key point here is whether you need to access only the client Routerboards themselves for management purposes, or whether you need to initiate connections to multiple addresses in their LANs from the central network, or even from one client’s LAN to another client’s LAN.
Regarding problems with clients A, B, C - what’s the difference between them? Are they three different devices (Windows, Mikrotik, iOS) at the same site, i.e. NATed behind the same public IP, or are they three Mikrotiks at different sites, each NATed behing another public IP?
Indeed, got carried away as I was typing, apologies … I will try to keep as short as possible the answers .
Yes
No
Exactly (3 Map Lite Mt’s, one at each site)
To access only the client Routerboards themselves for management purposes, you just have to choose a pool of addresses to assign them that will not overlap with the LAN subnet(s) of any of the clients. This is normally a non-issue if you are the administrator; if you are not, it’s more complex as each user is free to chose any LAN subnet from the RFC1918 ranges, and you probably don’t have enough public IPs to give out for that purpose.
If the connection requests from each of the three L2TP/IPsec clients arrive to the server from distinct public IPs, I have no particular idea what may be wrong. I’ve seen cases where certificates were used for authentication and caused the packets of the initial IKE exchange to be fragmented, which prevented the IKE from establishing because the fragments got lost somewhere on the way, and I have seen recently an ISP to filter IPsec transport packets encapsulated into UDP.
But from what you wrote, it seems like an “overconfiguration” to me, as you say you had to disable and enable peers and identities.
There are two ways to configure the IPsec part for L2TP, either you set use-ipsec=yes (or required) and specify the ipsec-secret in the L2TP configuration, and RouterOS creates all the relevant IPsec objects dynamically, or you configure the whole IPsec part manually, and then you must keep set use-ipsec at no in the L2TP settings.
So show me the current configuration of both the problematic clients and of the server (as text export, not as a ton of screenshots, see my automatic signature below). And explain how you’ve made sure that the initial packets from the clients reach the server through the NAT device that stands between the server’s WAN and the internet.
Thank you Sindy, for some reason I had left enabled the “use IP sec” in PPP/interface/dial-out (had manually configured IPSEC). After I disabled that, the link got established and is steady. All links between clients and Server are as expected.
3 questions if I may:
A) Why when connected to client1’s WiFi, I cannot connect to the Server through DDNS (WinBox)? If I try from my phone’s 4G I can. I understand that this happens because I am connected to that network, that has the L2TP link with the Server (and I can connect using server’s 172.21.69.153) but cannot figure out why I am losing connection through DDNS.
B) If I unplug a client from power (say for 15 minutes) and then power it up again, the link does not get established. If I enter client’s configuration and disable the peer and re-enable it the link is established. I thought that automatically this would happen (I mean the link being established after a power on). How can I have automaticaly the link established after a power outage (e.g. 2 hours)?
C) There is no need (at least for now) to access from client1 +> client 2, but should I need in the future, that would be a static route configuration between the three? Client1: 192.168.0.1 / Client2 192.168.1.1 / Server 172.21.69.153

Have fun with that Sindy, so many errors dont know where to begin…
I will point out that the wan port is on the bridge and he has ethernet2 on the bridge but both the bridge and ethernet2 have IP addresses.
Why all the partial nets of 192.168.0. - just use vlans so much cleaner.
Hi Anav, there is only one IP address 192.168.0.1 and that is of the bridge . Indeed all Ethernet ports are on that bridge.
The only thing to come to my mind is that you forward another TCP port than 8291 at the NAT device between the internet and the L2TP-server (mAP Lite) to port 8291 at the mAP Lite’s own IP.
When you connect from the LAN subnet of Client 1 to the public IP of the L2TP server site, the connection gets src-nated (masqueraded) to own IP of the Client 1 (493G), which makes it match the IPsec policy you’ve created to carry the L2TP traffic, and is thus sent via the transport-mode SA associated to the policy. The transport mode SA works as a src-nat and dst-nat, so at the mAP Lite, the packet coming through it is seen as coming from the public IP of the 493G to the private IP of the mAP Lite. Which is still fine, and the response would take the reverse path. But packets coming via the SA bypass the port forwarding rule at the router before the mAP Lite, so if you connect to another port than 8291 when connecting to the public IP of mAP Lite, the request arrives to the mAP Lite with that destination port unchanged.
If this is the case, it should be enough to restrict the IPsec policies at both the client and the server: at client, add protocol=udp dst-port=1701, and at server, add protocol=udp src-port=1701.
I can only imagine this to be related to the IKE session being established too early after boot.
So please show me the output of /ip firewall connection print detail where protocol=udp dst-address~“public.ip.of.server” at the client when it doesn’t work and when it does. There should be two to three connections, to port 500 and/or 4500 and to port 1701, and there should be a difference between the two results.
With the L3 tunnels between the clients and the server, the only thing you need to add are routes to other clients’ LAN subnets at the clients themselves, with the tunnel interface name or the remote address of the tunnel as gateway. The routes added at the server according to the routes parameters on the /ppp secret rows will take care about the rest.
But you’ve said before that you don’t plan any traffic between clients’ LAN subnets. Since you don’t exclude this for future any more, you have think about the IP address planning already now, so that no subnet is used twice in your whole private network.
A) Why when connected to client1’s WiFi, I cannot connect to the Server through DDNS (WinBox)? If I try from my phone’s 4G I can. I understand that this happens because I am connected to that network, that has the L2TP link with the Server (and I can connect using server’s 172.21.69.153) but cannot figure out why I am losing connection through DDNS.
The only thing to come to my mind is that you forward another TCP port than 8291 at the NAT device between the internet and the L2TP-server (mAP Lite) to port 8291 at the mAP Lite’s own IP.
When you connect from the LAN subnet of Client 1 to the public IP of the L2TP server site, the connection gets src-nated (masqueraded) to own IP of the Client 1 (493G), which makes it match the IPsec policy you’ve created to carry the L2TP traffic, and is thus sent via the transport-mode SA associated to the policy. The transport mode SA works as a src-nat and dst-nat, so at the mAP Lite, the packet coming through it is seen as coming from the public IP of the 493G to the private IP of the mAP Lite. Which is still fine, and the response would take the reverse path. But packets coming via the SA bypass the port forwarding rule at the router before the mAP Lite, so if you connect to another port than 8291 when connecting to the public IP of mAP Lite, the request arrives to the mAP Lite with that destination port unchanged.
The public port (that I forward from-Modem-to-MT is e.g. 7777), and added @ 172.21.69.153: chain=dstnat action=dst-nat to-addresses=172.21.69.153 to-ports=8291 protocol=tcp dst-port=7777 log=no log-prefix=“” . And chain=input action=accept protocol=udp src-port=1701 log=no log-prefix=“” , respectively with the same rule but with dst-port=1701 @ client1 and haven’t been able to access server MT through DDNS (Winbox) when the L2TP link is up. I can see packets received and transmitted via port 1701.
B) If I unplug a client from power (say for 15 minutes) and then power it up again, the link does not get established. If I enter client’s configuration and disable the peer and re-enable it the link is established. I thought that automatically this would happen (I mean the link being established after a power on). How can I have automatically the link established after a power outage (e.g. 2 hours)?
I can only imagine this to be related to the IKE session being established too early after boot.
So please show me the output of /ip firewall connection print detail where protocol=udp dst-address~“public.ip.of.server” at the client when it doesn’t work and when it does. There should be two to three connections, to port 500 and/or 4500 and to port 1701, and there should be a difference between the two results.

Yes there is no need like initially mentioned (but working it in my mind, there might be one in the future - only to access the MT’s, e.g. from client1 => client2 . I also thought to enter the static routes at each client and to test I entered a static route @ client1 dst address = 192.168.1.1 gateway: L2tp-out (couldn’t access client2) , I then entered 192.168.1.1 gateway: 192.168.90.1 (couldn’t access client2) and obviously I couldn’t ping it…so my guess is that the static routes on the server side are not taking take the “between”
A) The way you describe it, you’ve opted to use a dst-nat rule rather than to restrict the IPsec policy to carry only the L2TP transport packets. Nothing wrong about that. However, it then cannot be a matter of a bypassed dst-nat any more, but there may still be an MTU issue. I’d suggest to run /tool sniffer port=7777,8291 at both the client and the server and see what’s going on.
B) First you wrote that you have to disable and re-enable the peer at client, and now you wrote you had to disable and re-enable the peer at the server. Does either approach make it work?
Another point, I was expecting to see a connection towards port 1701 at the server IP at least in the case where it works, but you’ve only shown connections to/from port 4500.
If you only disable and re-enable the peer but don’t touch the /interface l2tp-client, what does the /ip ipsec active-peers print show while it doesn’t work?
If there is nothing in the active-peers list, or you keep getting some other STATE than established, you’ll have to create a large enough log buffer at the client, something like
/system logging action add name=ipsec-files target=disk disk-file-name=ipsec-start disk-lines-per-file=5000 disk-file-count=10
then, direct IPsec logging into that buffer:
system logging add topics=ipsec,!packet action=ipsec-files
and then switch the client off, switch it on again after 15 minutes, let it run for, say, another 2 minutes, then disable the /system logging item for IPsec and download the log files ipsec-start-xx.txt for analysis what is wrong about them
I was expecting to see some stuck NAT, but it doesn’t seem to be the case.
C) I haven’t checked your firewall rules. Again, sniffing is your best friend here, it will show you how far the packets get. If a packet arrives to some intermediate router but doesn’t leave it, that router may not have a route for it, a firewall rule in chain _forward_on that router may block it, or an IPsec policy may divert it into an SA; if a packet arrives to the destination router but there is no response to it, a firewall rule in chain input may block the request packet, an IPsec policy may reverse-match it (which means the packet is dropped if it doesn’t arrive via the SA associated to that policy), a route may be missing for the response, or the process expected to receive that request doesn’t listen (maybe because there is a restriction on addresses from which the requests are accepted).
Thank you Sindy for your continuous efforts to assist (and teach) !

I don’t see any connections nor packets involving the above mentioned ports …hmmmm
B) First you wrote that you have to disable and re-enable the peer at client, and now you wrote you had to disable and re-enable the peer at the server. Does either approach make it work?
Yes, that is correct…and then on purpose I decided to disable and re-enable on the server side to see whether the link be established or not. It did. So the result is the same on either.
Another point, I was expecting to see a connection towards port 1701 at the server IP at least in the case where it works, but you’ve only shown connections to/from port 4500.
I understand, This is the only connection showing regarding the link when : /ip firewall connection print detail where protocol=udp dst-address~“public.ip.of.server”
If you only disable and re-enable the peer but don’t touch the /interface l2tp-client, what does the /ip ipsec active-peers print show while it doesn’t work?
The connection from Active peers disappears. I checked this one through WinBox, so I assume that nothing would show when: /ip ipsec active-peers print
If there is nothing in the active-peers list, or you keep getting some other STATE than established, you’ll have to create a large enough log buffer at the client, something like
/system logging action add name=ipsec-files target=disk disk-file-name=ipsec-start disk-lines-per-file=5000 disk-file-count=10
then, direct IPsec logging into that buffer:
system logging add topics=ipsec,!packet action=ipsec-files

Without most making any sense to me, I have a feeling that there is a NAT issue causing it? Then again, why without changing anything, and by disabling-enabling the peer, it comes back on-line? I vaguely remember that during some tests if I unplugged and then powered back the client before the 10-minute DPD check (5 times every 120 seconds), the link would be established automatically…just in case it matters.
C) I haven’t checked your firewall rules. Again, sniffing is your best friend here, it will show you how far the packets get. If a packet arrives to some intermediate router but doesn’t leave it, that router may not have a route for it, a firewall rule in chain forwardon that router may block it, or an IPsec policy may divert it into an SA; if a packet arrives to the destination router but there is no response to it, a firewall rule in chain input may block the request packet, an IPsec policy may reverse-match it (which means the packet is dropped if it doesn’t arrive via the SA associated to that policy), a route may be missing for the response, or the process expected to receive that request doesn’t listen (maybe because there is a restriction on addresses from which the requests are accepted).
Let me work on the firewall rules and get back to you…all three MT clients + Server MT (and the rest clients in the future) are/will be behind regular ISP modems (modems take care of firewall rules, in the sense that they are not in bridge mode). Was looking/hoping to keep a very simple firewall rule table in the MT’s, under the understanding that MT firewall works in the opposite way than “commercial modems”, meaning allowing everything-unless-blocking-it …
