SSH droping connections over a VPN

Hello friends,

I'm connection to an external network using a VPN configured over an Ubuntu.

The problem is that whenever I get connected to a remote computer using my VPN as router, after a while, sometimes short, sometimes long, sometimes immediately, the connection gets lost and I've to reconnect to the remote computer.

I've checked the ssh configuration on the machine running the VPN and I think the error is not coming from that way, I'm guessing the VPN somehow fails and drops the connection, I don't think this is a networking issue either because I can be connected using another vpn program like Cisco's and the connection won't fail

Any information on how could I check where the SSH connection fails would be appreciated. also, if anyone has been in a similar situation and has information I might find useful would ve very welcome.

Thanks in advance

Without much activity the connection drop.
on the client side you could try to
Code:
ssh -o ServerAliveInterval=2

If it works you can set your ServerAliveInternal to whatever works (2 5 10 100 ?) in /etc/ssh/ssh_config

Basically it creates traffic to keep your session alive.

On the server side you could check or modify the ClientAliveInterval
