NT as a router

[Gareth]

Hi

Hope you can help me here I am trying to setup an NT 4.0 sp6a server to act as a router. I have never done it before and I am finding it abit of a struggle.

Right heres the spec!!!!

The server has 2 3com Etherlink 10/100 PCI NIC (3C905C-TX)cards installed. They are attached to different ethernet networks. I can ping both the networks from the server. How can I setup the server to let the two networks talk to each other i.e so one compter on network a can ping a computer on network B via the server. I have enabled IP forwarding. I am using Nebeui and TCP/IP I also have WINS DNS and DHCP installed on the server.

Please if you can help!!

Thanks in advance

Gareth

Well, it sounds like you've covered most of the bases from the server side. You can get to both IP networks from the server and you've turned on IP forwarding. (Not sure why you have Netbeui installed if you have TCP/IP working, but...)

The only thing I can think of to check is to ensure that the DHCP options are set correctly. You should have one scope for each IP network, and the Default Gateway for each scope should point to the appropriate network card in the server.

You didn't indicate what IP & subnets you are using. Both NICs need to be on different subnets and you should have a default gateway configured on one network (call it B network) and a blank gateway for the other (call it A network). You should add a static route for the gateway providing a route back to the A network. Run the 'route print' command and see what your routing table looks like. Also run the ipconfig /all and make sure just one gateway and different subnets.
Good luck.

Thanks for the advice!

I think what I am trying to do is a bit silly. Both network A and B are on the same subnet. But due to exec decisions they don't want them to be attached via our switch they want to use our NT server as a router? Yeah, seems a bit daft to me too.

So can I use a router to route packets this way? I don’t think I can

I have also got info from riproute.wri from the NT resource kit

If I have further problems I will be back. So, speak to you soon no doubt?
