Linux Firewalls that can connect to a domain?

Q. Hi all (again)

Anybody know of a linux based firewall that has the ability to connect to an active directory domain controller to authenticate users?

I have a Server 2003 Enterprise x64 Domain controller...

Anybody know of a firewall that can do this

PS: Can't afford Smoothwall!

A. First question, why would a firewall (network device) need to authenticate against AD?
If trying to control users in the Firewall with AD , try maybe Radius. There are a few free versions out there.

PS Smoothwall is "free", as most Linux firewalls. What may not be free is add-ons or support...

How much should an IT consultant charge to make a Linux based firewall out of an old computer?
Q.

A. How long will it take you and what's your desired hourly rate? Calculate that and you have an amount you're comfortable with charging a flat-rate for.

If you don't know what your hourly rate should be, do a quick search for a several reputable, local IT Support Providers and find out what they charge. Be competitive, but don't charge too low. Most responsible business owners want a qualified computer consultant over a "cheap" computer consultant. They expect to pay a fair and competitive rate. Not necessarily the lowest.

If you want to maximize your profitability on this project, up-sell a maintenance plan for the Linux box. Charge a low, recurring monthly fee that includes unlimited remote support, 24x7 monitoring and monthly reporting on service issues, bandwidth, security issues, alerts, etc. To push this solution, you can offer to discount the installation considerably, which you should easily make back over the course of the next few months.
