Nat and Firewall
Greetings,I'm setting up my linux box, now I would like to give internet access to the windows (brrr

I've installed and configured Webmin, and it come with a Linux Firewall button in networking section. As far as I can see it can be used also to do have a nat, but maybe you can tell me what software could be more usefull to do this.
I need to give my 10.10.0.0 255.255.254.0 users access to the internet. For someone I should open only the port 80, for some other 21 and 22, for some other realplayer or windowsmediaplayer ports, there is some software with an easy/clear graphical interface that work good? Or it is better to use a console program? What software you are using?
Thank you
