On my side I have ASA 5520 and on the other site there is a Checkpoint Appliance 4500.
We configure a site to site vpn with IKE V1 Sa Lifetime 28000 seconds and IPSEC Sa Lifetime of 3600 seconds.
The Tunnel works but, after 55 minutes there is a renew of the Key and the vpn goes down for 30 seconds.
The clients on the Checkpoint lost rdp connection with server behind ASA and the ping monitoring from my server to checkpoint clients stops witch "request timedout".
In the log I See:
6|Dec 04 2013|10:34:17|602304|||||IPSEC: An inbound LAN-to-LAN SA (SPI= 0xD9673E9D) between CHECKPOINT and ASA (user= CHECKPOINT) has been deleted.
6|Dec 04 2013|10:34:17|602304|||||IPSEC: An outbound LAN-to-LAN SA (SPI= 0x5F701F32) between ASA and CHECKPOINT (user= CHECKPOINT) has been deleted.
Dec 04 2013|10:25:37|IKE: Informational Exchange Received Delete IPSEC-SA from Peer: ASA; SPIs: eccb335c
Dec 04 2013|10:32:15|IKE: Quick Mode Sent Notification: Responder Lifetime
What can I do to troubleshoot this?
