Private Network - No connection to Internet.

Last Modified: 2012-05-10
I am working on a project where there will be no connection to Internet from my Servers 2 W2kSp2 and 2 W2kSp2 Ent servers and 6 workstations along with various other devices. Usually I would have a Router set as the Gateway.. But because there is no connection to the outside world I wont need this Router but rather something to act as the Gateway. So my questions is do I just use my Primary DNC's address as the gateway? What is the recommended way to set up a network when there is no Router connected to the outside? Any help would be greatly appreciated.

You dont NEED anything set as the default gateway, it will just mean that machines wont be able to communicate outside their subnet, but in your situation above thats fine... it will work.

You can setup routing on a server and use that, but unless you specifically need layer3 routing its no needed.

Not sure I understand. You say there is no connection to the Internet, yet you want to set up a gateway... If your network consists of only one subnet and is isolated from the rest of the world, then there is no need for a gateway.

If your network has somehow access to other subnets (or the internet) then indeed you need a gateway. You can configure your domain controller or any other server to act as that gateway by installing Routing and Remote access services.

Can you give us more info on how your network is connected to the rest of the world? Do you have some kind of internet access via a modem?

@vnicolae  -No connection via modem. Basically as it stands now I have all of the Servers/Clients connected to a Router but the Wan ports of the router are not connected. The gateway is being set via the router.

Then just configure all your clients and server to use the LAN interface of the router as their gateway. When the WAN ports will be connected, you will be all set.

As i said above and @macii2 mentioned there is no need for a default GW - if you have the router in your config as described then leave the GW as the router with the WAN ports disconnected - then its ready to go. You could configure one of the servers as DHCP - and remove the gateway entry to do this short term . .. there are many ways to accomplish it, but you need not worry about a defailt GW unless subnet traversal is required (other networks and/or the internet).

No requirement to fill gateway, you can leave this box blank as you are not connected with outer world
