I can right now reach from my OPEN VPN CLIENT ( iPhone 6 ) all the way past my OPEN VPN SERVER ( pFsense FW ) to my outside facing interface on my LAN ROUTER but not to the LAN BASED SUBNET it is HOSTING and running DHCP for.
Short version.
1.0.11.6 can ping to 1.0.10.12 but not to any address from the 1.2.3.0/24 subnet which is being leased from the R7000 RT.
