VPN, IP, Domain, Windows 2000 Help Please!

[LATech]

Hi,

This may be a bit long-winded, please excuse it before hand.

I am running a network with 2 different domains at a public school. 1 Server (Windows 2000 Server) runs our administrative side, and the other server (Win NT 4.0) runs our student side. Our Win NT 4.0 Server is our DHCP server. We are also using NAT on our CISCO T1 Router. I need to be able to assign a static IP (given to me by our local ISP) to both our servers in order for me to connect via VPN from home to either domain. My problem is, whenever I try to assign a static IP to my servers, the clients loose connection to the servers because they are still on my NAT assigned/DHCP IP range (172.XXX.XXX.XXX). Is there not a way to assign DUAL IPs for my servers? How do I go about assigning those static IPs to my servers, yet still use my DHCP/NAT for my workstations? What type of configuration do you recommend?
Any advice is welcome, and if you need more information, let me know!

Thanks!

You have static LAN IP (172.123.123.10, and 172.123.123.11) for servers inside the DHCP range of 172.123.123.12---254. (You better, servers should ALWAYS have static IPs.) Then you use Cisco router to NAT from your server static IPs to the public IPs by creating a static NAT map for the two servers (i.e. pub.lic.ip.1 = 172.123.123.10, pub.lic.ip.2 = 172.123.123.11) and a dynamic NAT map for the rest of the client (assuming you want them to share the T-1) of oth.er.pub.ip = 172.123.123.12---254. Now when you try to connect to pub.lic.ip.1 you are direct to server 172.123.123.10. Note: you better be sure of server security before creating a static map in the router!
