In the DMZ I have a Citrix secure gateway (CSG). When connecting from LAN to the CSG over HTTPS, these connections are dropped after about 5 minutes, even when the connection is active having traffic (ie. not idle).

When driving these same connections over a ZyWall with the same network and routing settings, everything works fine, tough.

Has anyone experienced similar problems or could anyone give me some hints on this issue? Has the pfSense some logic to drop HTTPS connections after 5 minutes?

I'd be glad for any help provided.

Regards,
Greg
