2003 Server as Router

HI All,

I have been given the task to setup a 2003 server as a router between
to internal domains on our network. I have never looked into routing
before so am having some difficulties working this out.

As I say we have two internal domains which I need to route to each
other. These domains both sit on different subnets. I have two NIC's
in the 2003 box one configured for each subnet. I have RRAS installed
on the server but that's as far as it goes.

From a pc on one subnet I can ping both NIC's on the server but cannot
ping any other ip address on the opposite subnet which leads me to
believe that I need to add static routes on the server but am not
sure.

Would be grateful for any help I could get on this matter.

Thanks in advance

Chris

How to Configure Windows server to Be a Router
RRAS is installed under w2k server by default, but not activated. To setup
Windows 2000 as a router for a LAN, you need to two network adapters.
To setup Windows 2000/2003 as a router for a LAN, you need to two network
adapters. To enable LAN routing. go to Administrative Tools>Routing and
Remote Access>Action>Configure and Enable Routing and Remote Access, and
then complete the wizard. Right-click the server for which you want to
enable routing, and then click Properties>General>Router, check Local area
network (LAN) routing only, and then click OK.

1. If the machines on each subnet use the Win 2003 machine's attached IP as
a default gateway, then no static route is necessary. If the gateway is
properly set and computers on one subnet cannot ping addresses on the other
subnet, then most likely LAN routing is not properly configured in RRAS on
the Win 2003 machine.

2. If machines use some default gateway other than the Win 2003 machine,
then you need static routes. You can configure these on the default gateway
router or on each individual machine.

3. If #2 is the case, try this test: On a workstation on subnet x open a
command prompt and enter:

route add <networkIPofsubnet y> mask<subnetmaskofsubnet y> <IPaddressof
Win2003>

eg. If the Win 2003's NICs were 192.168.0.1 and 192.168.1.1, a machine on
the 192.168.0.0 subnet would need this command:

route add 192.168.1.0 mask 255.255.255.0 192.168.0.1

If this works, you can make the route permanent by using 'route -p add'

Verify your router setup with this article. It is the same for either 2000
or 2003

To keep the rest as less confusing as possible:

1. All clients use the Server/Router as their Default Gateway
2. The Server/Router would have its Default Gateway pointing to the
Internet NAT Device (if thier is one immediately facing it.)
3. The Internet NAT Device (if their is one) will use "static routes" for
any subnet that in on the opposite side of the the Server/Router from it.
The Server/Router will be the Gateway for those routes.
