501 site-to-site vpn tunnel timeout

What is the maximum session timeout that you can configure on a site-to-site vpn tunnel using 2 pix 501s. 24 hours??

Thanks for any help, also, if you have documentation (I have looked but with no luck) could you post a link please....

There's no timeout setting as such. You can setup ISAKMP and IPSEC lifetimes though.

For Phase 1, default is 24 Hrs and "0" means infinte.

isakmp policy 1 lifetime 0

For phase 2 , default is 28800 seconds.

crypto map mymap 10 set security-association lifetime seconds 28800

HEre's the doc :

Re: 501 site-to-site vpn tunnel timeout

I have a similar setup but with the PIX 506. When I come in the morning I can see the tunnels are not up. We have DSL connections between the locations but once I initiate "interesting traffic" the tunnels come up with no issue.

Let me see if I can find a link to something that will help.

If you want them to stay up, look into dead peer detection.

isakmp keepalive
