how to deal with multiple public IPs to one router wan port ?

[scott]

Hi,

Im looking into getting a block of IPs in order to host several IIS
machines. At the moment I have one router directing traffic on port 80 to
one IIS machine.

Assuming I have many WAN IPs pointing to this router, how do I seperate the
traffic ?

Do I use static routes ?

How can a router have more than one WAN IP ?

I assume that the mac_address is used to direct all the IPs to the one
device.

Thanks for any help
Scott.

I just had a similar situation -- needed multiple public IP's to be
handled on one broadband connection for different web servers (IIS and
Apache) both on port 80. My inexpensive router doesn't support
multiple public IP's so I thought about doing this:

But then I found IPCOP (www.ipcop.org), open source Linux based
firewall gateway that I installed on an old box which now has three
public IP's.

Feel free to follow up off-line if you've questions about IPCOP.
