Had not looked at that option. There are a few of them. I'm no TCP
expert, but I'm a little skeptical that this will do the trick. The
timing from the firewall logs show a connection established and 2 mintes
later a teardown. That seems awful fast for a timeout. Which I'm just
guessing this is not.
I'll try it and see if it helps. It's a job that takes two hours!
