Hey all, I need a bridge for the following scenario:
[systemB] eth0 <--> eth0 [systemA] wlan0 <--> wlan0 [AP]
I am working on systemA, which normally sends dhcp requests answered by the
AP. I want to add systemB to that network. When it sends dhcp requests
over eth0, the AP should answer.
Bridging (i.e. brctl and friends) can only be used to connect two networks
that use the same layer 2 protocol. Ethernet and 802.11a/b/g do not use the
same layer 2 protocol. I believe at the very least you'll need to use an "ARP
Proxy", and you may be better off just routing traffic.
I *think* we have the reverse working: [laptops] <-> wlan0 [OpenWRT AP] eth0
<-> [AT&T Router], but I didn't set that up, so we might be having the AP run
a dhcp daemon and route traffic.
