Running an IIS 6 Windows 2003 Server behind a SOHO Firewall

Hello guys/gals!

I have an issue that I have to resolve fairly quickly and I need your help.

I have a Windows 2003 Server box behind a Watchguard Firebox SOHO 6. It does not have NATs. I am hosting websites with IIS 6 and am under the impression that using host headers is the only way I can use the existing firewall because it is capable of only having one external (public) ip. I know I can cut the firewall out of the picture and enter my alotted public IPs on the servers NIC and assign each website a unique IP, but I want to use the firewall for obvious reasons and can't upgrade right now.

I have one IP assigned to the network card (192.168.111.7) and under IIS 6, I have two websites that are both set to "All Unassigned." In both websites I have host headers set up like this: "domain.com" and "www.domain.com" both on port 80. I have both set up with index.html as the document to load when a request comes through. Both websites point to different directories.

I have the firewall accepting incoming http requests and sending them to 192.168.111.7 (the server). In addition, I have an ftp server set up using IIS 6 as well with a static IP of 192.168.111.7. The firewall is accepting incoming ftp requests and sending them to 192.168.111.7.

I have the 2 domains registered with Network Solutions and my ISP provider has created records for the 2 domains leading to the firewalls public IP.

Am I doing someting wrong? If I'm missing something that I need I would really really appreciate it if anybody had any clues!

Thanks in advance!
Bobby

If I may ask a tangential question based on your post.

I was just wanting to comfirm that II6 and 2003 Server will accept a private IP ( on the Servers Nic) for the public web site as long as that private IP is routed to the firewalls public IP.

Thank you Very much

I don't have 2003 but IIS5 and 4 work fine from the public internet with the server on a private 192.168.x.x IP

Did you ever find a answer to this? I have a IIS 5 server that seems happy accepted NAT connections from external clients but my IIS 6 server doesn't ?

Thanks
