BOVPN error "No response for IKE_SA_INIT request message": UPDATE: issue SOLVED
I've this error after build up a BOVPN between a T20 and T15 Firebox but it's very strange because both Firewalls are reachable over public ip addresses, I can login into both of them and also in both firewalls I've already configured three others BOVPNs that are working properly. I've checked the max number of VPNs in my license and it's ok, I've removed and recreated the BOVPN that isn't working but without success. I've also upgrade OS to the latest possible version but without success.
UPDATE: issue SOLVED
