Good morning, strangely one my vpn site2site stopping to work. The error message I get when I try to begin a new session is: "Unable to resolve peer GW (VPN Error code 02)".
I found nowhere any indications about the cause of this error, could you help me?
The encryption domains are coherent on both sides, on my side we have a CheckPoint over Nokia, on the other side ... I don't know.
Best regards Marco
Probably we found the problem: on our firewall there are two site2site VPN, on both of them there is the same network family (to be sincere with different subnet masks ...)
VPN1 = 172.30.0.0/16 VPN2 = 172.30.4.181/32 + 172.30.4.195/32
Removing the larger mask from the first encryption domain we got no more errors. It seems that the firewall detect a conflictual setting and doesn't take any decision.
