Q: KeepAlive not working

My laptop (Debian Woody unstable) is behind a Linksys router acting as
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.
