ASA 5505 Dropping Connection

[Mark1818]

dieselboy-

Hey thanks for the help on everything.. after investigating with IBM a couple things, it turned out to be a combination of the ispection rules on the firewall as well as the ibm client access terminal sessions keep alive needing added to each computer's config file. and updating the TCP/IP in windows registry to add the line KEEPALIVETIME=60000 for (60 sec) decimal

Everyhing is up and running normally now.. I appeciate the insight and have saved all the info if anyone else needs, or runs into this problem with remote connections back through to an AS/400, or similar using a client access product, etc.

Thanks again.

Can you tell me what changes you made to the inspection rules?

Kind of sounds like the ASA maybe expiring the connections while they are idle. Some applications won't send packets often enough to keep the firewall from aging out the connections. You may want to take a look at the below link as it explains how to configure it:
