When pinging from a LAN device on Side A (Windoze Surface using cmd, 192.168.2.184) behind the gateway 192.168.2.10 (which can ping both the remote devices tested below) are the results.





Device 192.168.1.3 on the remote side (side B) is their ClearOS machine hosting the configuration that connects to side A. 192.168.1.181 is a tablet device behind side B's ClearOS router (192.168.1.3)

The above ping results are the same from a LAN device on Side B's network pinging 192.168.2.10 (Side A's gateway/OpenVPN server) and 192.168.2.184 (Windoze Surface with firewall set to respond to pings from outside its own LAN subnet).
