I was under the assumption that when you change the WAN IP address due to ISP change, that will break the VPN due to peer ip change.
The history of all of this is that my client has an HA pair of 1120 appliance cluster in Nigeria on R77.20 and are in the process of changing their ISP. Now there is a VPN link between Nigeria which is the satelite, and London cluster which is an HA 5000 cluster on R77.30 the hub, all managed by an R80.10 virtual management server.
I have managed to split the Nigerian cluster, and placed one of the cluster members on the new ISP WAN IP. Now I want to move the other cluster member which hosts the VPN link between Nigeria and London, to the new ISP WAN IP. My query is how do I reinstall the VPN link, should it break due to the WAN IP change?
I contacted Checkpoint TAC and they refered me to their local office and they categorically stated that I would need SmartLSM to reinitialise the SIC between the Nigerian cluster running R77.20 and the centrally management server running R80.10.
Any information moving this case forward would be appreciated.
