sessions disconnects when login to my server that is behind the ASA

[hossam.shibl]

Hi all,

   I have ASA 5510 that is connected with its inside interface to a database server and the inside hosts. I have a public ip that is natted to the private ip of the server so that the outside users can login onto it. the problem is that the session disconnects when idle for around 10 minutes. i tried to make the timeout to infinity but in vain. the same problem still found. Can anyone help me to solve this problem.

BR,

Hello,

Could you post your current configuration? What kind of connection is establiushed to the server, that is, TCP or UDP? Do you see any syslogs when the connection times out?

Regards,

Also let us know about the timeout log you see.

You don't have tcp connetion timeout set.

What timeouts are these, is the ASA responsible?

You need to find the teardown log on the ASA to see what is happening exactly and if it an ASA timeout that kicks in.
