Session expires after 30 minutes

Hi, I have in the DMZ a leased line connection to a branch office. In the branch office there is an application to the AS400 (central Site). The application uses the ports tcp/1025 and tcp/23 (telnet). I have the problem that the session to the AS400 times out after 30 minutes. I have set the ttl to 14400, but session still goes down after 30 minutes. config system session-ttl set default 3600 config port edit 23 set protocol 6 set timeout 14400 set end-port 23 set start-port 23 next end edit 1025 set protocol 6 set timeout 14400 set end-port 1025 set start-port 1025 next end You got an idea? Thanks, Judit

Are you 100% sure that the session expires on the central site FGT? If you look up the session table in the 31st minute (after session has been cut), is the session really not in the session table any longer? It could as well be the application (terminal emu) that forces an idle timeout. In my experience session TTL limits work well, and every time.
