Hi,
I am facing issue with one of the VPNs setup for our customer. Once the tunnel is established, it works fine. But I suppose during the SA re-keying the ASA detects duplicate messages from Checkpoint and the tunnel is dropped briefly. Eventually one of the SPIs is accepted and the tunnel comes up without any intervention.
I have compared the VPN config with the remote end and it seems to be correct. The renegotiation timings are as follows:
Phase 1 Renegotiation time: 1440 minutes
Phase 2 Renegotiation time: 480 minutes
Also find the attached logs from the ASA where,
A.A.A.A is the IP of the Checkpoint firewall
C.C.C.C is the IP on the ASA.
B.B.B.B is the server IP behind the ASA and D.D.D.D is the server IP behind the Checkpoint firewall.
Any suggestions are highly appreciated.
