Kevin,

if You are willing to use Linux as a router, let it do address
translations, i.e. use private addresses in Your network, and only on Linux
translate them into public IPs if needed. This will spare as much ip
adresses as possible (btw. You can think over port translations if one
doesn't need a public IP but a few ports only)

I'm setting up a wireless ISP and I have a few routing questions. I am
setting up a Linux computer as the router, but what I would like to do
is conserve as many IP's as possible. I have one subnet to work with,
and the less number of IP's that get wasted on bridges, access points,
etc. the better. The internet comes in thru DSL into the router, which
takes care of traffic shaping, routing to the correct AP, etc, etc.

What I am wondering is, is it possible to put all of the AP's, bridges
and the router's ethernet cards that connect to the wireless network on
a private subnet, and then give the customers a pubic (internet) IPs?
Would a tunnel have to be set-up to accomodate this set-up? If so, what
tunneling method would you reccommend? Or, better yet, am I taking the
wrong approach to this set-up? Is there a more established way to run
this type of network?

Thanks in advance.
Kevin Brown.

You need some address on your network to act as a router for the
clients, and that needs to be on the same network from which you
give addresses to the clients.

Other addresses (switch/router management addresses etc) can (and
to some extent should) be on some other network - and the private
ones are ok for this. Even infrastructure service machines (like
DNS servers) can be set up with private addresses (for the client-
facing direction). It'd be good to declare to your customers which
internal network address spaces you're using - just to avoid
possibility of conflicts.
