RRAS Basic Firewall and multiple public IP's

[Frank]

Here's my scenario - I have a Windows 2003 web server with 5 IP
addresses. I want to allow HTTP, HTTPS and FTP on each of those IP's
and block everything else. When I configured RRAS, I selected "Basic
Firewall" on the "NAT/Basic Firewall", and then checked the HTTP,
HTTPS and FTP services on the "Services and Ports" tab. However, when
you check the services you want to allow, you also have to enter a
"private address". This is where I get stuck.

Since I have 5 IP's, I would ideally like to enter 5 IP addresses
there, or a range of IP addresses. To me it looks like I will have to
add a new HTTP, HTTPS and FTP service for each of the 5 IP addresses.
Is this the only way or is there an easier way to configure RRAS to
allow the same port on multiple different IP addresses?

Any help would be greatly appreciated.

You are talking about port forwarding. Its intended purpose is to allow
incoming traffic to a single destination on your private LAN. there
shouldn't be a need to have to add all 5 IP addresses.

If your concern is additional load on the server, having 5 addresses isn't
going to help you ( you should implement another server and configure load
balancing between these two ).

What is it you are trying to accomplish exactly?
