Application Timeout !!!

Hi All ,

Just a small query , I have a PIX to PIX (site to site) VPN and I am able to successlly ping the server at site B from any computer from site A , but the main Application is loaded in the server at Site B.

The client Applications are loaded on all workstations on Site A.These applications tend to time out after 5 minuites of inactivity , these are Oracle based Applications called IFS which runs from the client machines.

I have done a continious ping ( with the ping x.x.x.x -t ) option in the Dos prompt of the client machine , and then run the client application , the Ping gets a continious reply but the application times out after 5 min.

Is it to do with any ISAKMP lifetime on the firewall or what I am not understanding , The Application works fine without any timeout on all the local machines at the Site B where the server is actually located.But from the machines on site A it times out ........

Any idea why It could be , or is it a VPN issue or an Application issue......

Please give your advice.....

Re: Application Timeout !!!


The ISAKMP lifetime is for the key exchange , it will not affect your application timeout.

It more likely the application issue. I think you might need a sniffer trace to find out what is the "keepalive" packet between the client and server.

If it is a multicast or broadcast packet, it will not pass through the VPN tunnel.

Because IPSEC VPN tunnel only can pass the unicast packet.
