BOVPN Randomly dies and only failover fix it.
I have issue with s2s vpn to a checkpoint that drops after a while, some times it works for days and then dies. Now other VPNs also do the same. The other end are Meraki and Cisco ASA.
Rekey dose not help and only failing over the cluster fixes the issue.
Troubleshootins that been done so far:
First it was on Ikev1, changing it to Ikev2 did not help.
Used different SA Time, Hash,encryptions, Still problem.
Tried it with DPD On and OFF, not helped.
Changed the MTU on ext int to 1400, not helped.
Changed the Don't fragment (DF), tried all 3 options ( Copy, set, clear), still same issue.
WG support could not find the issue either. By this time i have gone thru the configuration 100 times everything matches.
I'm so close to lose my mind!
