We have what I would call a sensitive application that is somehow losing it's connection when Phase 1 re-keys on the VPN tunnel the traffic is being tunneled through. I think it's likely a combination of gateway/tunnel settings that could be modified but also just a sensitive application. The application disconnects were a mystery at first until we closely correlated these to the phase 1 re-keys on the VPN tunnel through which the traffic is passing.
Any information on what we might be able to monitor or modify in these VPN tunnels or gateway settings would be much appreciated. The tunnel setup is on R80.10 management and HA gateway using ClusterXL. We have Clustered gateways on each end of the VPN tunnel and have VPN tunnels to multiple sites. We have staggered the re-keys to no avail...thinking it was somehow tied to the multiple satellite gateways and the central gateway was not able to handle the multiple re-keys. This staggering re-key change did not improve the application disconnects.
