[ILUG] Wireless networking

[Michael Jonker]

You could probably achieve what you want by some mechanism on your 
broadband router (which I assume is the wireless access point?), but 
this can be dangerous (and will vary from router firmware to router 
firmware) as you could accidentally expose your whole server to the 
internet WAN.

A neater and safer way to do it is to get a combo [wireless access point 
and LAN router/ switch] + an additional ethernet port for your server.

Turn off the wireless on your internet router and let it do only 
internet (WAN) traffic through the firewall on your server. (on ethernet 
1, external network).

Your new network router/switch can now direct all traffic (wired or 
wireless, on ethernet2, internal network) to the internet and intranet 
through  the security mechanisms you have set up on your server.

I recommend that you look at something like Zentyal (formerly Ebox, 
built on Ubuntu) for your server as it makes setting this up user friendly.

There are probably other ways of doing it, this is just how I do it.

Good luck,

Michael Jonker
