I recently added a new subnet of servers in a remote site and tried to add a VPN tunnel to access them. The VPN connection was previously in use and is working for some of the routes but not all. I have Watchguard x5500 at both sites.
The Office -> Remote DC looks like: 192.168.40.0/24 <==> 10.0.10.0/24 192.168.40.0/24 <==> 10.0.20.0/24 192.168.40.0/24 <==> 192.168.10/24
The Remote -> Office lookls like: 10.0.10.0/24 <==> 192.168.40.0/24 10.0.20.0/24 <==> 192.168.40.0/24 192.168.10/24 <==> 192.168.40.0/24
The 10.0.x.x/x routes are working correctly. The new subnet (which works fine locally) does not connect. I cannot ping or talk to those servers in anyway.
Anyone know a good way to troubleshoot BOVPN tunnels for Watchguard?
