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.
So, is it possible in any way (preferably simple) for systemB to send a dhcp
request and get a response from the AP? I have dnsmasq running on systemA, so
I can set it up to do something. Do I need a "dhcp forwarder" of some sort?
