TheCat12

That is the more fortunate situation because you can do the following: For the server you can add one of the addresses directly on the Ethernet port facing it. For the VLANs and other NATted subnets you could add routes pointing to their gateways with dst-address being a public IP: /ip route add dst...

You still have to answer my question whether both sides of the L2TP tunnel are MikroTik routers because routing will be made on the router with the public IPs

As for the communication between the LANs, it should be quite an easy fix: # Server /ip ipsec policy add action=encrypt proposal=ike2-proposal src-address=192.168.200.0/24 dst-addres...

TheCat12

I have nothing to add. Even if the code is bad-shaped, which it is not, what matters most is that it works.

P.S. For your information, what you have achieved between the routers is not a L2TP tunnel but rather an IPsec tunnel

TheCat12

I wouldn't classify the topic as "Beginner Basics" but who am I to judge?
Anyway, is the router part of the backbone or a different area? Do the timers match?

An exported config would help finding the cause of the problem:

/export file=anynameyouwish (minus sensitive info)

TheCat12

Without config we can't tell anything...

/export file=anynameyouwish

TheCat12

Someone was in a hurry to fix it:

Screenshot_20240724_200744_Samsung Internet.jpg

TheCat12

I'd suggest using the following IPsec policy on the local router:

/ip ipsec policy
add action=encrypt src-address=192.168.1.0/24 dst-address=171.11.153.20

And one with swapped source and destination addresses on the remote party

TheCat12

1. Your firewall filter is a self-hazard - better use the default one than this open door for attacks, malware and what not 2. The accept mangle rules aren't necessary 3. You're missing two routes: /ip route add dst-address=0.0.0.0/0 gateway=100.94.144.1 routing-table=main add dst-address=0.0.0.0/0 ...

TheCat12

Because I forgot that a route should be added on Site A:

/ip route
add dst-address=192.168.1.116 gateway=<l2tp client interface>

TheCat12

Just one question - is a default route to the gateway needed? As the AP de facto acts as a switch, shouldn't routing be handled by the gateway?

TheCat12

Don't forget to assign the DHCP client on the bridge and not on ether1 or better yet, assign the address that is currently on ether1 on the bridge and don't add a DHCP client and:

7. Delete or disable all default routes if there are such existent

TheCat12

In the dst-nat rule you haven't specified dst-address (i.e. your static public IP), against which the packets should be matched so that their destination address is accordingly translated. Also, port 22 is SSH, so you better change your dst-port (the more obscure, the better)

TheCat12

/routing table

If we consider the default bridge as WAN and the IoT as LAN, change the default bridge to be part of the WAN interface list and remove out-interface=ether1 from the masquerade rule: /interface list member set [ find interface=bridge ] list=WAN /ip firewall nat set [ find out-interface=ether1 ] out-i...

TheCat12

And make sure not to run a DHCP server for the 172.17.0.0 range on the branch office router as it may lead to undesired effects

TheCat12

It probably happens because the addresses of local and remote LAN are the same. I think that could be overcome with the help of an EoIP tunnel spanned over the L2TP tunnel but that would require a static address for the branch office router instead of a random one from the VPN pool: # Head office /p...

TheCat12

I can try to help you with that problem too - firstly you have to turn on IP firewall for the bridge: /interface bridge settings set use-ip-firewall=yes After that add a firewall to drop all forward for the PBX address except for in-interface-list=PPP: /ip firewall filter add action=drop chain=forwa...

TheCat12

You could also remove the add-dst-to-address-list rules because they should be covered by the mangle

TheCat12

Yes, quite a nice and proper correction

TheCat12

I'll once again try to rewrite and rearrange your mangle rules so that hopefully everything works after that. In my previous posts I was pretty sloppy about the order of the rules on which I emphasized earlier that it is of importance (shame on me) and probably that's the reason why you lost remote ...

TheCat12

Perhaps the problem is in the firewall. That's why it's not good to work with sniplets of config. Would you export your whole config and post it here?

/export file=anynanmeyoulike (minus sensitive information like serial numbers, public IPs, etc.)

TheCat12

One minor suggestion - remove the dst-address-lists of the "X only VPN" rules (rules no. 12,13,14) so that all traffic originating from the VPN can be matched against them, not only destined to the addresses in the lists. Also you could combine rules no. 15-20 by using in-interface-list=LA...

TheCat12

I see that you've reverted to the old naming convention for the routing tables and marks. That's why I'll suggest once more to change it as in the previous sniplets of configuration. Bear in mind that you should not only change the names of the routing marks but also that of the routing tables to ma...

TheCat12

Perhaps exactly that is the problem - the ports that should be used to access the server are changed so that the outside users don't know the original ones

TheCat12

I think that there is no need for egress-vlan-translation and that is causing the problem: When an entry is created under /interface ethernet switch ingress-vlan-translation , then the switch chip will add a VLAN tag on ingress frames on the specified port. To remove the VLAN tag on the same port f...

TheCat12

The VLAN is a side note.

However, I just saw that you haven't specified the to-ports parameter in the dstnat rules. Maybe that is the cause

TheCat12

More likely what @karlisi suspected - you're behind the ISP's NAT which doesn't have full port forwarding enabled, hence no access to the server from the outside

P.S. Your VLAN is not configured properly

TheCat12

For the firewall filter rules I forgot that the order in which they are is of importance baecause the matching is dome sequentially. That's why the drop input expecr from LAN should be after all other input rules and analogously for the drop forward from WAN except dst-nated rule. As for the three s...

TheCat12

Use action=src-nat in the srcnat rule so that you can specify to which port should the IP address be sourcenatted: /ip firewall nat add action=src-nat chain=srcnat protocol=tcp src-port=5060 src-address=192.168.7.100 to-addresses=222.222.123.2 to-ports=5060 Just make sure to put the rule before any ...

TheCat12

The only thing you should change from the screenshot config is to remove in-interface=bridge . If you have a static public IP, you could use it in dst-address instead of in-interface-list=WAN. If the rule still doesn't work, maybe you're behimd carrier-grade NAT and you should ISP to create a full p...

TheCat12

Your firewall still lacks some essential rules, for example dropping all input not coming from LAN (a default config rule): /ip firewall filter add action=drop chain=input in-interface-list=!LAN Another one is drop all forward from WAN not dstnat-ed: /ip firewall filter add action=drop chain=forward...

TheCat12

One way would be to use a DNS record - for example the one from IP/Cloud, which you could add in an address list and use dst-address-list instead of a dst-address. Another way is the one you mentioned - create a DHCP lease script. There is no better or worse way

TheCat12

For the UPnP to work, you need to add interfaces: /ip upnp interfaces add interface=ether1 type=external add interface=bridge type=internal enable 0,1 Otherwise all ports are open by default, to forward ports you need to add dstnat rules: /ip firewall nat add action=dst-nat chain=dstnat protocol=udp...

Perhaps it is missing NAT?

Also, remove sfp-sfpplus1 from the bridge as well as from the bridge VLAN table and VLAN 1 from the latter, and everything should be fine

Only exception on the remote router is that in this case policies with action=none shpuld be a...

Maybe to better understand what you try to achieve a simple network diagram would be needed. Also, does VLAN 30 arrive at the Mikrotik as .1Q tunnel and which are/should be its inner VLANs?

One of the problems may be that your LAN network's addresses overlap with those handed out by the Starlink because, if I remember correctly, it is CGNAT. Nevertheless, an export of the config is advisable for us to be able to help you:

TheCat12

Although it "doesn't exist from source" as you refer to it, it does get introduced by being set as vlan-id in /interface bridge vlan and/or pvid in /interface bridge port, depending on the role of the port, and the VLAN tag begins being added/stripped after enabling vlan-filtering

TheCat12

For option 1 I disagree that there is a need for a VLAN200 interface because the VLAN should operate only on L2, no L3 needed. That's why I omitted it from my config

TheCat12

Isn't there a src-address option in the /radius menu?

TheCat12

A side question - why do you use a public IP (170.x.x.x) for LAN?

TheCat12

Ok then, first you'll create a bridge with all ethernet ports except ether1 in it (for the config I'll assume all ports are ether1-5), then create a VLAN interface for VLAN 20 and configure IP addresses and DHCP settings for it. After that you'll fill in the Bridge VLAN table and enable vlan-filteri...

TheCat12

So VLAN 20 is for the "normal" internet, I assume? And the DHCP server for it would be the Mikrotik?

There is an easier hairpin NAT rule:

No need of mangle whatsoever

1) Yes, because this is a whole other method which has nothing to do with the switch one 2) It is advisable for ether2 to be on a seperate bridge even though it is one port 3) Yes, but you could limit the traffic from VLAN 20 to the other VLANs if it's necessary from the firewall: /ip firewall filte...

The explanation is that your router most probably acts at the moment as a switch (I assume all ports are bridged together for the computers to get an IP address from the same range as the WAN).

TheCat12

I think it won't be possible to separate the subnets on the antenna, but rather on the access point because the antennas act as a wireless extension of the ISP modem subnet and also don't have enough interfaces to do routing on them. That's why you should make the AP the DHCP server
