How does 802.11a/b/g come into this? Yeah, that's just me not reading carefully. But looking at the first post by the OP, I thought that ath0 was meant to join eth1 and eth2.

Of course ARP happens on top of the link layer, just as IP. But ARP is a requirement for IP traffic. And by faking ARP answers for the computer in the other subnet, a router can redirect IP traffic to itself. It just claims all addresses in the other subnet. That's what "proxy_arp" does. So when it in fact uses forwarding, it behaves similar to a bridge w/ regard to that you don't need to configure all the computers with a route to the other subnet. > In *any* case, it's extremely unlikely that the OP is going to be carrying > any significant amount of non-IP traffic.
