RE: [FW1] telnet lose connection after idled

[Greg Blake <greg@FW1-NOSPAMhealthgate.com>]

I'm not sure if that will always help.

I've started running into a similar situation since we upgraded to 4.1 sp3.
I used to be able to connect via ssh to hosts out on the net and stay
connected all day long.  (Not an idle connection) and I've noticed that now
my connection gets dropped randomly after a few hours.  It will even be
while I'm typing that it will go away.  It is getting quite frustrating.
