[olug] Wireless bridge

[Luke-Jr]

A literal wireless bridge requires the router to support (and allow) WDS with 
your specific client. Many routers do not support WDS, and most consumers do 
not know how to configure it if it is supported.

A common workaround is known as an ARP relay, where the "bridge" presents its 
own MAC address to each end for the other end's IPs. ARP relay only deals with 
ARP itself, and therefore will NOT bridge non-IP protocols such as DHCP. So 
the "bridge" would also need a DHCP relay, or its own DHCP server.

Personally, I tend to use ARP+DHCP relay for wireless-to-wired bridges, and 
WDS for wireless-to-wireless bridges (aka range extenders or simple meshes).
