TCP Connections drop after 60 Seconds

[PerryDz]

I have a Contivity 1010 which works fine and I am able to setup VPN tunnels from remote Contivity VPN clients. I have a problem that while the tunnel is solid and stays up forever applications that I have running(i.e. SQLPlUS, Terminal Server Client etc.) have thier connections disconnected after 60 seconds of activity. There was another thread(thread902-1099370) posted about this earlier but I have seen no responses to it. I can find no setting anywhere to configure this. Any help would be apprecitated.

What code are you using?

Are you saying the client apps disconnect from their sessions but the tunnel stays up? What is the status on the contivity after the clients disconnect? Do the routes still exist?

Check PFS, compression and vendor id? Should be the same on the either side.

I think I have a similar issue with Oracle. My oracle sql session get "disconnected" while idle. I think it has to d with the ports getting closed by the contivity. let me know if you can find the fix.

Yes, the client apps disconnect but the tunnel stays up. The routes do still exist. Following is an example using Oracles sqlplus application.

1. Execute SQLPLUS application.
2. Run sql commands within the SQLPLUS application. All works fine.
3. Leave idle for 60 seconds.
4. Attempt to execute sql command withing the SQLPLUS application.
5. Fails.
6. Exit from SQLPLUS.
7. Execute SQLPLUS.
8. Run sql commands within the SQLPLUS application. All works fine again.

This behaviour is not specifice to SQLPLUS. It happens with all applications that have established a connection with a server and are left idle for 60 seconds.
I have tried with two different groups - one running IPSEC and the other PPTP and the same thing happens with both.

Thanks for your advice, I will check these things.
