Hi, this is my first post on this forum

I have Routerboard 450G with routeros 4.11 L5, and problem with vpn tunnels.

It's possible to run two l2tp client intetfaces on sam router?

Yes, it is possible. There are no limitations how many clients you want to run.

I ask because when it works only one L2TP client everything works ok, when I create a new interface L2TP-client one that worked immediately terminated and can no longer connects.

Make sure you have static routes to both l2tp servers.

Yes I have route to both l2tp servers.

My situation is:

I have two location with two ISP on both location, one is ADSL and second is cable internet, and that is on both location, and on all address is static not dynamic.

I want to make redudant vpn tunnels between that location. One side is a l2tp-server side other side is client side.

When i set one l2tp tunnel it's work perfectly, and when i make another l2tp client interface, firs tunnel brake down and not work.


........... /ISP1 -------l2tp1-------------ISP1\
Mikrotik1 -------------------------------------Mikrotik2
............. \ISP2--------l2tp2-------------ISP2/

l2tp-server side ............................. l2tp-client side

Make sure your l2tp server gives to every client connection not only different remote addresses, but also different local addresses.
