1 Router, 1 IP and 2 NICS

[romh]

Hi. I was reading an article on techrepublic on configuring a VPN server. I have a Windows 2000 AD at work and would like to connect from home and share a drive. I have not been able to this yet. But if someone could clarify this issue, it would help alot. Part of the instruction says the following:
You need to install Windows 2000 Server and the latest Service Pack on your machine. Make sure you don’t install other unnecessary services, such as DNS, DHCP, and IIS.

"During installation, you should choose to statically assign IP addresses. You’ll need to set up one network card with a true Internet IP address and the default gateway of your Internet router. The other network card should have an IP address assigned to the local network, and it should not contain a default gateway."

At work, I have a linksys router with a 16 port switch. The router is the one with the true internet IP address. and obviously in charge of giving every computer internet access. My question is the following:
With only 1 static IP address at work (given by the ISP), how can I set up a NIC with a true Internet IP address if the router is the one with that IP address. Do I need to forward it to the VPN server? I am very unclear.

Any help would be appreciated.

Thanks

yes, forward to the windows VPN server. quoted form

Which ports need to be opened for running VPN

A: PPTP VPN uses TCP Port 1723, IP Protocol 47 (GRE); L2TP: UDP Port 1701; IPSec: Pass IP protocol 50 and 51. Note: 47 is a protocol number and not TCP port. The protocol name is GRE. It'll make a big difference when configuring your firewall or router.

Thanks alot. very good website. Let me add a couple of things. I have a Windows 2000 Adv Server at work that serves at web server, file server and AD. I also added the VPN to that same server. I am able to connect successfully from home, but I cannot view any of the files or shares on the server at work.
Is this because my configuration / forwarding is not correct?
I already have the AD server serving as web and file server with the appropriate ftp and http ports forwarded to that machine.
So you are saying that if I add another computer as VPN server, I simply have to forward the correct ports/protocols to that machine. And I can still do all of this with 1 true IP address?

What exactly is a protocol number? How do I forward that? I am very new at VPN's and have been researching alot, but still cannot solve my problem.

Any other clarifications would help. Thanks

if you can access the VPN, forwrading is no issue here. Can you ping the server aftre establishing the VPN?
