[K12OSN] Outside access to K12ltsp intermittently cut off

["Terrell Prudé, Jr."]

I would look at /var/log/messages on the firewall computer and look for 
any iptables messages.  I don't know if ShoreWall does packet filter 
logging, but if it does, you'd want to further grep for the IP address 
of the outside box from which you're trying to connect.

Also, what do your firewall rules actually say?
