Linux Help

Hi,

I'm new to Linux, so i'm paling to install a gateway, with the following,

1. Firewall
2. DNS
3. DHCP
4. SMTP (relay only)
5. Email Virus Scaning
6. Gray Listing (email)
7. NAT
8 Web Cashing
9. Web Based Configuration tool for all above.

can any one tell me the best Linux version to use, (RedHat, Debian, etc)
and the software i can use, like DNS = BIND, some thing simple to use...

the Box will be a P2 with 256MB ram but if i can get it to work on a P1
166Mhz that would be great....

thanks
Kev
