We have two offices connected via Gateway-Gateway VPN
DC2 is able to connect to DC1 just fine using the private IP Address of 192.168.0.101. Of course this works because DC2 sends all traffic to pfSense as it's gateway and PFSense sends traffic to the local RV082B. There is a route because of the VPN.
The problem that we are experiencing is that the branch firewall has no knowledge of the subnet behind pfSense.
Somehow we need to add a route from the branch firewall so that it knows where to send traffic.
We basically just want to be able to ping, RDP, etc to 192.168.1.2 and DC2 being the recipient. Its a challenge now that we have pfSense in the way. Its almost as if we have two firewalls. We don't know what to do because we really installed pfSense just for its captive portal capabilities.
