Further issues with IIS
Please see this question for an explanation of my setup. https://www.experts-exchange.com/questions/21536734/IIS-and-VPN-on-same-WAN-connection.html
I have resolved the networking issues by adding a switch. It connects the existing network to the cable modem, and should connect the new server to the cable modem, but doesn't appear to work. When I configure the server with the proper static IP/DNS/Gateway/SubNet information, I'm unable to see it from outside the network. In fact, if I leave DHCP enabled, it actually finds our DHCP server and obtains an IP. This means that the server is finding the VPN/router and the rest of the network, and using it. As far as I understand, this shouldn't happen.
Has anyone had a similar experience? I'm getting to the end of my neworking knowledge, and am running out of ideas.

Thanks Pete, but I managed to figure it out. It had something to do with the patch panel I was running through to connect to the switch. I ran a new cable directly t the switch, and I appear to be good to go. I have a second NIC installed that allows me to connect to this machine through our network. Am I running any kind of hacker/intrusion risk with this setup?
I'll be happy to award you the points, but I'm wondering if you wouldn't mind giving me your opinions on firewall software? I have to install something, but I'm not sure what the consensus smart choice is for people who are "in the know". I have PCcillin antivirus on my home PC, and like it. I also hear they make a good firewall product, but the only FW experience I have is XP SP2. I've also heard bad things about Zone Alarm and it's interaction with windows update. Any opinions?

You are correct that the new server should not be able to get an IP from your inside DHCP server. When you configured the new server with the static IP address from your ISP were you able to ping the new IP address? If you can ping the address the server is responding correctly.
What is the address range of you DHCP server (internal) and what is the address the new server is getting when you enable DHCP on it?
If you tried to hit the server using a browser through the Internet, you will have to modify you DNS records at your 'registar provider'- the company who hosts your domain name and DNS records. A new name record will need to be added to the effect of: "www.mynewserver.com" equals Public IP xxx.xxx.xxx.xxx
Your layout should be something like this:
cable modem----LAN Switch----Cisco PIX----Internal LAN Switch
|---New Server NIC card, Public IP
If you want my email is: pete@technetconsulting.net
We can do this offline & I can post the results as we figure it out.
Thanks
