FYI, that doesn't require the router to have a unique IP.

I must admit that I've never used proxy_arp, but all ARP traffic occurs at the ethernet layer, below the IP layer, so it doesn't make sense to me for an option/program so named to only work on IP traffic. ARP is also only used intra-subnet, so this entire section doesn't make much sense to me. In *any* case, it's extremely unlikely that the OP is going to be carrying any significant amount of non-IP traffic. I feel that is an extraordinary enough condition to be mentioned. > I've never used a switch before.

Generally a switch will have no configurable software; if it has anything worth configuring the manufacturer will call it a router and add 10-15$ to the price tag. In any case, I doubt you'll find a switch that supports 802.11a/b/g, since they will always require a little bit of configuration (ESSID and keys). You could get a wireless router (e.g. Linksys' WRT line), but they will have some software configuration. If you choose the right model, it'll be Linux instead of proprietary software. However, I know of no wireless routers that come from the manufacturer with Gentoo installed. In fact, I'm fairly sure that Gentoo doesn't provide any profiles, support, or even instructions for running on such hardware, which has severe [compared to a desktop] hw limitations. -- "If there's one thing we've established over the years, it's that the vast majority of our users don't have the slightest clue what's best for them in terms of package stability." -- Gentoo Developer Ciaran McCreesh
