Hi team.

We have various WiFi devices connecting in the house, as well as my main PC, my brother-in-laws PC, and now my friend/neighbours PC all connecting via wifi.

I would like to build a box (linux preferably) to manage all this, especially with regard to the following:

bandwidth - I want to limit brother in law and neighbour to 1.5GB data each month.
logging - i want full logging of who does what (@ss covering really).

I take it i will need to get a seperate ADSL modem from my router, and plug them in via 2 seperate network cards in my new box for a start?

What specs am I looking at? Will a Pentium 200 do for this project?

This is something I -need- not a project that i really want to dedicate time to - would anyone build/configure one for me for a price?

Is there any out of the box software that anyone can reccomend? (Clarkconnect??)

Thanks guys.

I'm not sure on the bandwidth quota, but the basic configuration is pretty simple.

As a suggestion it would probably be an idea to post on the NZLUG mailing list (

The mailing list has quite a few people on it and if you start a thread you should get a few suggestions on implementation.

A few suggestions on the basics would be:
* Yes, you'll need two network cards. 1 to lan (with wifi AP's on it), 1 to ADSL modem.
* An Ethernet based ADSL modem is your easiest to configure, but you can have problems if you need to run services/forward ports into the network, especially forwarding from modem -> linux box -> internal machine. Gets a bit troublesome over time.
* Logging can be done to an extent. SMTP (email) and HTTP (web) are most likely the main areas you want to log. If you operate transparent proxy services on the router you can log all of this in the process. Logging other information including all inbound/outbound connections can be troublesome. NTOP can be good for this though, but depending on the volume of traffic it's memory usage can grow very quickly.

The configuration is pretty common though and someone can probably point you in the right direction from the NZLUG mailing list. There's also a few localised mailing lists/LUG's aswell so you might be able to find someone in your area that will do it for you.
