I'm trying to configure Windows 2000 Server (SP4) as an IP router. The box that 2000 Server is installed on has 3 network cards. I've setup two private networks that can talk to each other using the 2000 Server as a router. Network card 1 has the IP: 10.10.0.10 and a 255.0.0.0 mask. Network card 2 has the IP 172.17.2.10 and a 255.255.0.0 mask. Both of these nics are attached to separate mini switches. These mini switches have other machines connected to them.
The machines on the switch attached to network card 1 are all in the 10.10.0.0 range. The machines on the switch attached to network card 2 are all in the 172.17.2.0 range.
The devices on either range are able to ping each other just fine.
Network card 3 in the 2000 server is attached to a Cisco switch and has the ability to get out to the Internet. In actual fact, this Cisco switch is behind a PIX firewall, and the PIX is attached to our 3620 router which is connected to our ISP. Network card 3 has the IP 192.168.4.10 with a 255.255.255.0 mask.
The 2000 server can get to the Internet and browse web pages fine. However, neither servers on the 172.17.2.0 range nor 10.10.0.0 range can get to the Internet.
What I want to end up with is the 2 private networks behind the 2000 Server to talk to each other and the Internet.
I've installed Routing & Remote Access Services on the 2000 Server, but I don't know how to get the routing setup on the server to function as I require?
Please can you help me get this working. Please feel free to reply with any questions you may have about my setup that I haven't covered above.
Thanks in advance.
