VPN with AS400 connectivity

[e-see]

I have a PIX (6.3.3) configured for VPN access for 4.x.x clients. When remote users access the AS400 using Client Access the session disconnects after a few minutes. I can still ping the AS400 and if I re-start the client all is well again for a few minutes. Rest of network is fine. Thanks

Do you have the stateful firewall enabled within the Client? I had the same problem. It went away after I disabled the firewall.

Which client?
