Forwarding port 80 traffic to different web servers

Hi. I have a Windows 2003 with NAT that is acting as a firewall. The
internet interface has multiple IP addresses. In the internal network, there
are two web server PCs. We want to redirect port 80 traffic coming from
outside to both web servers depending on the IP address used. Is this
possible?

If the web servers will have different IP addresses, use the
"Reservations" in NAT to reserve two public addresses and map these to the
web servers' LAN IPs. All traffic for each web server will be forwarded to
the LAN address.

Port mapping is handles by special ports. But this is only used if you
want to map traffic coming to the same public IP by port number (eg send tcp
port 80 to one LAN IP and port 1723 to another).

Yes. Use the RRAS console - expand IP Routing and click on NAT/Basic
Firewall. In the right pane right click on your Internet interface and
select properties.

On the Address Pool tab you can add addresses and map them to specific
internal IPs and/or on the Services and Ports tab you can map ports for
specific public IPs to internal IPs. You can add as many port 80 mappings
as you want.

Thanks guys for the replies. I think I'm now on the right track.
