What are the default VPN tunnel lifetimes for both Phase 1 and Phase 2 in a Cisco ASA 5505?
We have a Sonicwall NSA 4500 setup with a site-to-site VPN tunnel to a Cisco ASA 5505. We are experiencing issues where the tunnel stops responding after exactly 32 minutes. It goes down for a few minutes and then comes back up for exactly 30-32 minutes again. I cannot tell precisely how many minutes but by the time we are alerted it shows to be 32 minutes. The 32 minutes is always a constant regardless of lifetimes set in the Sonicwall though the time the tunnel stays down varies according to the lifetimes I set in our Sonicwall. I have read online that the Cisco is very picky about lifetimes matching on both sides. I am unable to contact the techs at the company on the remote side. Can someone please let me know the default lifetimes, whether it is 86400, 28800, 3600 or some other value, and give them for both Phase 1 and Phase 2. Thanks!
