I have 2 sites that I am trying to connect via a BOVPN tunnel between our 2 Fireboxes with the same trusted internal networks. Settings are:
Firebox x750e Fireware 11.4.3
Firebox x550e Fireware 11.4.3
Site A is our production environment and Site B is a Disaster Recovery Site. The tunnel is primarily set up to allow our production SAN (192.168.7.50) to replicate to the DR SAN (192.168.7.51). The replication is currently working locally but we are now moving it to the DR site. We have a PC set up on the DR side (192.168.7.11), as well.
I have configured the gateway and tunnel but the tunnel shows as inactive. I have tried various configurations, including enabling the 1to1 NAT on the tunnel but still cannot get the 2 sides to communicate. I know this is because of being the same internal network settings b/c if I reconfigure the DR to use 10.0.0.0/16, the tunnel works fine. We need to have the same internal networking though.
