a firewall (all ports from inside allowed out, only 22, 80, 443
allowed from outside). When I ssh to machines inside the LAN, they
never disconnect. If I connect to a machine outside of the LAN (DMZ),
it hangs after about 5 minutes of idle time, despite the fact that I
have "KeepAlive yes" in my sshd_config file.
I imagine that it have something to do with my Linksys box, but I
can't figure out what.
Re: Q: KeepAlive not working
KeepAlive will turn on TCP keepalives, which by default are 2 hours
apart. You can try ClientAliveInterval (server side). Debian also
ships with a third-party keep-alive patch for the client side, but I
don't remember the option for that (check the man page for ssh_config).
There have been at least 3 other reports of LinkSys-related SSH problems.

Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
