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 this 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 3.18 - “Routing” 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.
