I am very interested in using NT as a firewall and rather than everyone   
getting into debates about the "perfect firewall" and operating system   
should there be a separate list for those who through desire or necessity   
have to use NT as their firewall platform? Then there could be detailed   
discussions of the practicalities of implementation. Anyone willing to   
offer a mail list for this purpose or know of one that already exists?   
Volunteers no doubt would like to contact Brent to know what they are   
letting themselves in for.

I know that no doubt there are dangers of assuming an OS is good enough   
and blindly ploughing in but I assume some firewall manufacturers are   
willing to stake a reputation on producing products and being able to   
evolve to counter new threats. No flames please.
