MikroTik

I was directed here after starting a post about this very same issue. I've got the same problem with the same hardware combination.

Has anyone heard any official word from Mikrotik about this?

michaelcarey

An interesting read indeed!

I guess it's time to contact my Mikrotik vendor and see what happens.

Hi Everybody, I've got a roll-your-own Wireless Access point here at home based on a Routerboard RB912UAG-2HPnD (802.11b/g/n) and a recently installed R11e-5HacD miniPCI-e card for 802.11ac capabilities. It's been working very well for the last few years in 802.11b/g/n mode, very stable. Of late, I'...

Add a specific route for each remote IP to use the EoIP interface and make sure you source NAT only targets traffic leaving (out) the other interface with dst address of 0.0.0.0/0 (default). This will make the routing side source the EoIP traffic to originate from the right IP and prevent it from b...

michaelcarey

MTU changes when you enable IPSec but the default value should function. The addresses you gave are private IPs. If they are really private IPs can you draw a picture of how these devices connect. EoIP (GRE) doesn't place nice with NAT but it is possible to traverses it (1:1 NAT). IPSec however wil...

Hi Everybody, Some time ago I successfully had an encrypted EoIP tunnel between two Mikrotik routers (together with IPsec encryption) working over a public WiFi network. Since V6.37 (I think), I've not been able to get it working with IPsec. I'm using the IPsec Secret field in the EoIP Interface to ...

Hi Everybody, I have recently started experimenting with bonding between an RB2011UAS and a CRS109-8G-1S-2HnD. There are two Cat6 cable runs between the two locations. I have 802.3ad bonding working between the two devices and am using a bridge to connect the bonding interfaces to other hardware Eth...

I confirm, I have the same problem with RB750

And me too... my RB750 had interfaces going up and down after upgrading to v6.31.

Everything fine after going back to v6.30.2

michaelcarey

yep, that should work

Thanks for that... I'll give it a go.

michaelcarey

If I understood correctly then just look at dynamically created ipsec peers. one should be with address 0.0.0.0 other with eoips remote address. But since L2TP client uses the same IP address then of course peer setting with more specific IP will be used not 0.0.0.0. So obviously in such setups you...

michaelcarey

EoIP and L2Tp connects from the same IP?

Yes... the client I used for testing is "behind" one of the routers that hosts the EoIP endpoint, NAT would make it appear to have the public IP address of the router. The public IP addresses are used at each end of EoIP.

michaelcarey

I added the IPsec key option to my EoIP tunnel interfaces... and it seem to break the L2TP server. :-( EoIP works fine with IPsec. "Windows error 792: The L2TP connection attempt failed because security negotiations timed out." Is an IPsec enhanced EoIP tunnel mutually exclusive with an L2...

michaelcarey

Thanks to all who offered input to this question... and thanks to cdemers, adding a Source NAT/Masquerade rule was the solution I was looking for. This in effect treats the ADSL modem IP address/network as another "internet", NAT translates my private home IP addresses into the 192.168.1.0...

michaelcarey

Does the TP-Link respond on its IP address whilst the PPPoE session is active? If so, it should just be a matter of adding an IP address in that network on ether6 on the RB2011 and away you go... Thanks for the reply troffasky. Yes, the TP-Link ADSL modem does respond on it's IP address (default is...

michaelcarey

Hi Everybody, I'm after some suggestions on the best way to configure RouterOS/Routerboard so I can access an ADSL modem web config from inside my network. My main router is an RB2011UAS, my ADSL modem is a TP Link TD-8840 in bridge mode. Ether1 is the main internal interface, it is connected direct...

michaelcarey

Very nice indeed!

The bend radius on some of the Ethernet cables seems a bit tight though.

Michael.

Hi Everybody, I am trying to set up a 3G internet connection using a Huawei E173 "dongle" on my Routerboard CRS125-24G-1S (RouterOS 6.18). I've done some Google searching but can't seem to find a solution to this problem, nor does it appear that anyone else is experience the same symptoms ...

michaelcarey

michaelcarey,
Enter this command to fix it on CRS125:
Code: Select all
/interface ethernet switch port set [find] learn-restricted-unknown-sa=yes

Yay !!

Problem solved! Thank you so much!

Is this something that was introduced when I upgraded to v6.10? Will I need to worry about it again?

Michael.

michaelcarey

Since upgrading to v6.10, my CRS125-24G-1S seems to be acting more like a hub than a switch! My normally quiet home network has become VERY busy! I had a quick search through this thread and couldn't find anyone with my symptom... sorry if I missed it. Port 1 is connected to an ADSL router. Port 2 i...

michaelcarey

I believe I am experiencing the same issue on my newly IPv6 configured RB2011UAS-RM. v6.4 I've been playing with IPv6 on the RB2011UAS for a little less than a week, and it's been working very well but today it just stopped. My ISP also hands out a dynamic /64 IPv6 prefix for the PPPoE session and I...

michaelcarey

A Netinstall recovery has brought the RB2011UAS-RM back to life... I'll place it back into operation in a few hours (from typing this reply) and see what happens. The LCD screen operation has also returned to normal. I presume that the 100% CPU load affects the way that RouterOS interprets touch fro...

michaelcarey

I seem to have just experienced this exact symptom on my RB2011UAS-RM. Prior to this I was noticing that the LCD screen was not responding to swipes and this morning I noticed 100% CPU Usage. My next thought was to perform a reboot (via winbox) and now I am stuck in a boot loop. I get up to the stag...

michaelcarey

Well... things are not good. Started looking at bit more at my RB2011UAS-Rm this morning, hoping to get more info on the touch screen issue and noticed that the CPU Load was 100%. Tried a reboot and now my router is stuck in a boot loop. (this is described in another thread). My impression of my new...

michaelcarey

Hi Everybody, I'm a new RB2011UAS-RM owner/user. So far I am quite impressed with this router although I am finding I cannot get a gigabit link to my Linksys switch (not a deal breaker though). Today I have noticed some strange behaviour with the LCD touch screen. It no longer appears to respond to ...

michaelcarey

Here is my Mikrotik RIC/522 5.8 GHz installation. Link distance is around 2.5km. This equipment links my home network to my ham radio D-Star/IRLP/AIS/telemetry/video equipment at my comms site. Much cheaper than maintaining another ADSL connection at the remote site. http://vk5rex.squarespace.com/st...

michaelcarey

What is the "official" word from Mikrotik on this problem? I don't really need my RB2011UAS to connect at Gigabit speeds but it would be nice if it did!

What happens if it's a hardware issue? Do we all get replacement Routerboards?

michaelcarey

OK... I have solved the problem! It was nothing to do with the RB2011UAS or the configuration! The thing that cured the problem was a reboot of the NAT router between my home network and the public WiFi network. I'm not sure exactly what might have been going on inside that prevented me from establi...

michaelcarey

Hi Everybody, A long post... but I hope you can indulge me! I've just installed a Mikrotik/Routerboard RB2011UAS router at home. This amazing unit is replacing an aging Snapgear/Cyberguard router. I'm after some guidance on how to solve an unusual PPTP VPN implementation/configuration issue. I've co...

michaelcarey

Apologies for the tardy reply to this follow up to my question... I've been tied up with doctors, hospitals, poking, probing and other things that I would have preferred to stay away from. I've Googled "mikrotik one on one NAT" and couldn't really see how to use it in my application. It se...

michaelcarey

Hi Everybody, I want my RB750 router to handle two ADSL connections. I don't want anything like load balancing, each connection will remain separate. Two ADSL modems, two PPPoE connections, two ADSL accounts, two ISP assigned public IP addresses... this is straightforward and fairly simple to set up...

michaelcarey

Oh yes... please don't misunderstand.

I really like Mikrotik... very powerful.

Mikrotik and Routerboard!

michaelcarey

You didn't post your config, so my asumption was that 'exchange-mode=main l2tp'. WinXP L2TP/IPSec client requires this mode an registry modification as described in mentioned MS KB articles. Good to know that it works for you :) Regards, In the Mikrotik online manual "chapters" referring ...

michaelcarey

OK... I looked a little more into the thread I posted just above and found this post :- Hi .. I had the same problem when using IPsec/L2TP and NAT-T I resolved this by changing the IPsec > Peer > Exchange Mode from "main" to "main l2tp" This revision allows the the FQDN as the pe...

michaelcarey

Thank you for the reply. I think I have seen one of these KB articles before. Q818043 (I think) does not apply to me as as according to the article, this update has been already been applied with SP3. Q240262 seems to be for Windows 2000. Does this KB article still apply to WinXP? I do agree that it...

michaelcarey

Hi Everybody, I've set up an L2TP server on a Mikrotik/Routerboard RB750 (PPPoE ADSL connection). Everything seems to be OK, I'm using a pre-shared key. I've configured the Firewall/Filter Rules to allow UDP 500,1701,4500 and protocol 50. I can connect to it with the two Win7 machines in my home off...

michaelcarey

Hi Everybody, I've done more searching and can't seem to find anything specific to my question... I apologize if it's been covered before... I couldn't find it. I'm setting up another RB750 router for use with some amateur radio VOIP servers (again). It's a basic NAT router config with a PPPOE conne...

michaelcarey

Thank you very, very much.

Hi Everybody. I am a RouterOS newbie so please be gentle. So far I have my RB750 set up with a PPPoE connection to my ISP, set up NAT, prevented external access to the RB750 via the internet and set up port forwarding to various PC's on my internal network. It's working very well. At the moment my e...

Did you try to find answers here: http://wiki.mikrotik.com/wiki/Main_Page or here: http://www.mikrotik.com/docs/ros/2.9/ ? Yes, I have even printed out the documentation and studied it quite a bit. BUT, I am hesitant to purchase a licence for Mikrotik if I am not sure that it will do what I want/ne...

Can any kind person help me out with this? Please....

michaelcarey

Hi Everybody, Sorry for the long post, it's my first!! I'm a long time MikroTik user. I haven't used it for anything overly serious so far, mainly as a network monitor, allowing me to see at-a-glance which machine on my network is up and down, performing pings and the like. Anyway, I have a far more...
