Hello! I have Mikrotik as L2TP Server and Teltonika RUT240 as L2TP client. On previous firmware everything seemed to work. After the update to latest firmware I have created an L2TP Client and added a route to the remote network.
The Mikrotik network is 192.168.0.10/24
Teltonika network is 192.168.3.1/24
L2TP server is 192.168.20.1, vpn clien 192.168.20.16.
From RUT240 the connection is established to the Mikrotik router. But routing doesnt work. I can ping VPN address of RUT240. But i cannot ping 192.168.20.1 (mikrotik side of vpn tunnel, "destination port is unreachable"), i cannot ping 192.168.0.10 and i can not ping and of the ip addresses on Mikrotik network. The same applies to Mikrotik side (can ping its VPN address, but cant ping RUT240 vpn addres, local address and any of network addresses).
Perhaps this is routing of firewall issue.
Where should I look at?
