Hello, On a bridging firewall using ipfw I noticed that ssh conections get hung after an inactivity period. On some tests, tcpdumping the connection between two FreeBSD machines, both client and server with ssh "KeepAlive yes", I don't see any kind of keep alive traffic. dyn_ack timeout could be raised, but doesn't seem a proper solution. Any ideas on why ssh is not sending keepalive packets? Thanks! Fernando P.
