Question regarding NAT session timeout

Is it possible to set the NAT session in PAT to a value other than the default? I'm running an application for testing and it looks like everytime the sessions expires, it goofs up!

I have been searching cisco documentation for a command where I can set the session to something like 20 minutes or more but cant find it...any help will be appreicated

You may want to look at the "ip nat translation" settings you can adjust. Just a warning though...setting them to high could cause your router to slow down or even crash due to lack of memory.

You really need to have a good reason to do this. I don't think it is recommended. I actually had to adjust these settings today but I had a very real business reason for it. I would be careful as wasted said since memory isn't unlimited.

I agree with those above.

If you're testing an app that's supposed to work through NAT, tell the programmers to send keep-alives so that the NAT session doesn't time out.
