You will protect the Server, but not you internal Network. Since an Software
Error on the WWW-Server will expose your complete internal network to the
Hacker.

Why do you want to masquerade the Server?

Yes, but with Linux you can't do static NAT (at Least not with the stable
Kernel). Therefore you will have to use a TCP-Proxy or

Usinf Squid as a WEB Enhancer, which is a rather good Solution for
Performance, but not the mostz secure. Using http-proxy from TIS Toolkit
would be a rather secure thing. netcat or tproxyd can be used to Map Port 80
on the Firewall to Port 80 on the NT Server, too.
