multihomed server as router for two local networks and internet

by kaesid . Updated 17 years, 5 months ago

Hi there everyone,

I was hoping someone could shed some light on a situation I’ve been running into.
There are 2 local networks, each one is an autonomous domain (subnet mask: 255.255.255.0 , local networks: 192.168.0.1-100 and 192.168.1.1-100)
Also there is a server (microsoft server 2003) for routing between these 2 local networks and the internet
Each of the local networks has 6 legal ip (internet) addresses
The server (as router) has to provide to each local network access to the internet and to the website of another local network
The server has 3 nics that configured as follows:

NIC1
ip 192.168.0.1
dns 192.168.0.2/192.168.0.3

NIC2
ip 192.168.1.1
dns 192.168.1.2/192.168.1.3

NIC3
ip legal external ip
dns dns of ISP

NIC3 shared
both local networks configured their tcp/ip with default gateway that is an appropriate (from the same network) NIC from the server

I can’t seem to figure it out. I would really appreciate some help. Thanks.
