[NCLUG] ipchains question

[Mark Sizer]

Hi all,

I have to admit, I joined the mailing list just to ask this question. 
However, I will remain subscribed and do my humble best to offer any help 
I may. I'm not much of a Linux guru, though.

I've probably waved at some of you, you occasionally had meetings in our 
office space when I worked at Velocity.com (the first dead dot com I 
worked for).

Anyway:

I have a Linux server connected to my cable modem. There is a Windows 
2000 server hiding behind it. The Linux box has two network cards, 
firewalling the Windows machine (sort of - more of a router. I'm afraid 
my security is not very good).

I've got the Linux machine masquerading the internal network. It works 
fine.

What I want to do is allow access to the Windows web server from outside. 
I assume this means routing a port on the linux machine's external card 
to 192.168.0.2:80 on the inside. I've tried numerous things, but I've 
only managed to kill sendmail.

Could anyone help, please?

Thanks,
