Hi Mohammed,

Yes, traffic logically go though Firewall, firewall as the gateway.

Hi Noel,

Are you sure that the ASA drop the ssh session? how? any logs?

Is the session drop when no traffic? or what?

Hi Noel,

Try to change the tcp timeout global configuration which will resolve your ssh timeout issue. The default timeout is 30 min.

timeout conn 1:00:00 half-closed 0:10:00 udp 0:02:00 icmp 0:00:02

Plz rate if its helpful.

Hi

what type of SSH software are they using ? it could be that the software is not sending keepalive packets.

If it is possible then you can set the software to send "keep alive" packets to keep the tunnel active even if the user does nothing for a while.

fx in putty this is done under connection and there you have

enable tcp keepalive

and

sending of null packets to keep session active

set this number to fx 50 ie 50 seconds between null packets to be sent within the keepalive.

Good luck

Hope This Helps
