I've been having the same problem recently, since I upgraded from 4.0 sp3 to 4.1 sp2 (NT4 Management and 2 Nokia 440's running IPSO 3.3) It looks like I've managed to fix it with the help of Phoneboy (searching for Unknown TCP packets) All you have to do is uncomment a line in the $fwdir\lib\fwui_head.def and the line is #define ALLOW_NON_SYN_RULEBASE_MATCH Basically, what this does is to revert back to the 4.0 way of handling connections in the state table. I had to make this change under intense pressure from 'the business' as 90% of our users and external clients were being kicked off their connections to an AS/400 box. I still have reservations about the fix (for security reasons) but didn't have a choice.

The users are accessing an application via telnet on the Unix server which controls a printer located outside the firewall. These users access some sections from this application and send information to the printer, they receive the following problem: When they try to print some information, the printer starts printing the job but after 2 or 3 minutes the telnet session to the server suddenly stops and it stops also the printing. I think this a TCP timeout problem, however I'm using some configuration documents from the CheckPoint support web site in order to increase this tcp timeout value but I keep receiving the same problem. I don't know if I'm missing some steps on the configuration of the TCP timeout, or if it could be a timeout on the same Windows NT operative system. Any similar experience?
