Why not just turn on the ssh and sshd keep-alives?

sshd_config:
ClientAliveInterval 60
ClientAliveCountMax 30

ssh_config:
ServerAliveInterval 60
ServerAliveCountMax 30

These settigns will send a packet every 60 seconds to keep the NAT
state fresh when using a losing home NAT box (like the wrt54g when
running factory firmware).  As an added benefit after 30 minutes of
dropped packets the program at each end exits.

I used to have a problem with a buddy that had one of the above
routers that would complain that my system's sshd dropped him after 10
minutes of inactivity.  I sent him a ps showing that he had 6 sshd's
still active here waiting for his next input.  After I added the
sshd_config settings his connections stopped dropping.
