My guess would be that you need to enable TCP/IP Keepalives.

Subject: [THIN] Tough one!
A short description of my problem:
I have a relatively small LAN with approx 50 users, i have divided the
LAN into two, and seperated them with a firewall (security issues). The
firewall is a plain Linux firewall with masquerading, and IPv4
Ip_forward. (the firewall acts on behalf of all the clients, as if all
clients on the inside had one "outside" ip address")
My problem occurs when one of the clients goes idle for about 10-15
minutes: The client get a message indicating that the Terminal server
has ended the connection The console on the server still indicates that
the client is idle, but the truth is that it has been disconnected for
some reason. If i log on the user again, the session which still is
indicating an idle session, remains untouched -and a new active session
is created. (this also result in a lot of cpu usage, if the user log on
and on and on and on, as a result of the disconnect.)
Then to the really annoying part of this issue:
Both the domain administrator and the local administrator (of the
terminal server), can stay idle for 2 days without getting disconnected.
I have tried to make a domain user a member of the domain admin/local
terminalserver admin group, but with no luck. The normal user (with
administrator
priveliges) still gets disconnected.
Then to the REALLY annoying part of this issue:
If i move the client to the other side of the firewall, everything works
fine. I assumed it to be a firewall problem until i figured out that the
domain admin and the local admin (of the terminal server), dont have a
problem.
Summary:
Inside of the firewall:
Domain admin works fine
Local admin of the terminal server works fine
Domain user does not work fine
Domain user with administrator priveliges does not work fine
outside of the firewall:
Everything works fine.
Anyone know how to fix this problem?
A possible solution could perhaps be to keep the session from turning
idle, but i havent figured out a way to do this. If the user works
continuously, he/she will not experience any problems. The problems
occur after beeing idle for about 10 - 15 minutes.
