Bridge vs Router
Each WI-MOD-E is configured with an IP address for the Ethernet side, and another for the wireless
side.
A
Bridge
connects devices within the same Ethernet network - for example, extending an existing
Ethernet LAN. For a Bridge, the IP address for the wireless side is the same as the Ethernet side.
A
Router
connects devices on different LAN’s. The IP addresses for the Ethernet and wireless sides
are different.
In the above example, the wireless link is part of LAN A, with the Client unit acting as a Router
between LAN A and LAN B. Alternately, the Access Point could be configured as a Router - the
wireless link is then part of LAN B.
If more than two routers are required within the same radio network, then routing rules may need to
be configured (refer section “3.11 Routing Rules” for further details). There is no limit to the number
of Bridges in the same network - although there is a limit of 128 Client units linked to any one Access
Point.
