L2TP always disconnecting after 75 seconds

Hello,
i’m searching the forum, but i can’t find a solution for my problem.

Two CCR-1009 Router ( Ver. 6.32.2 ) wants to connect via L2TP Tunnel. But after the L2TP Client is connected, the connection terminated always after exactly 75 seconds. After that, the connection will be established again and break down after 75 seconds. And so on…

I have another MikroTik Router in this network (RB 2011). Connection to this Router are without problems.


I will send the file exports soon…

I found the mistake.

I try to route the same network through the L2TP Tunnel which was reached to build the L2TP Tunnel. Oh no…

Thx
