Bridging is not enabled over both the LAN and the WAN.

Check the Local Site > Bridge and Remote Site > Modify screens and ensure that bridging is turned on over both interfaces and that the remote site is enabled.

The IP network is not responding because the OfficeConnect Remote 840 is trying to route IP packets, instead of bridging them.

Check the Global > IP > IP Settings screen and ensure that IP Forwarding is disabled.

The IP network is not responding because the LAN IP addresses are assigned on a different network than the remote address.

When bridging IP, the local network becomes part of the remote network and must be assigned addresses on the same network or sub-net.
