I have a firewall, where I have to lower the TCP session timeout from 24h to 1h.
Before I do that, I'm trying to determine if this will break any applications, i.e applications that have sessions that can be idle for a long time, but are not able to re-establish the connection if the firewall drops it.
So I want to filter out connections from my connection table, that have been idle for more than 60 minutes.
Firewall is CheckPoint R75.40, and I'm looking at the connection table with the "fw tab -t connections -u" command. I suppose the information I want is in the output, but what am I looking for?
