Except that this doesn't work on WLAN (MAC layer done by the WLAN
adapter). But probably "proxy_arp" can help here. And subnet
separation, of course. Just extending the netmask a bit and enabling
proxy_arp would do the job. OTOH, it's also easy to configure the
routes to the other subnets via DHCP. Just a matter of taste. In any
case, it only works on IP layer.

Sounds like I'm getting in over my head.  I think it would be smarter
for me to buy a $15 switch from NewEgg instead of trying to configure
my Gentoo router to use its extra NICs this way.  Is there any reason
I wouldn't want to do that?

I've never used a switch before.  Is there any proprietary software to
configure (like with a router), or is it just a button or two?  I like
to keep my non-Gentoo software to a minimum, hence the Gentoo router.
