Adding router to network switch

[NthDegree]

We are currently running a LAN with a Windows 2003 server and a few Windows XP Pro computers using a Dlink switch.

We are using static addressing with the server being 172.16.0.1 and the other computers using 172.16.0.x.

To give us internet access we have installed a DSL line/modem and a wireless/wired router (The router is configured with PPPoE and DHCP and has four wired LAN ports). Each PC has a ethernet NIC and a wireless NIC. Ethernet NIC is used to talk to our internal network and the wireless to the router.

Ok, now for the question.

We would like to be able to get rid of the wireless NIC's
and plug the router into our network so the computers can get to the internet over our LAN. How can I configure our computers to get to the internet in this configuration?

Ultimate solution would involve our server handling the forwarding.

Any suggestions or advice would be appreciate.

The quickest way would be to plug the switch into the router and enable DHCP on the nics. This would allow access to the internet but would not involve the server.

I'm not sure I know what you mean by enable DHCP on the Ethernet NIC's. We are using static addressing on our LAN.

Easiest way is to take one port on the current switch for the LAN and one from the router's switch ports and daisy chain them together.

So your connection would look like this:
DSL>Modem>Router>Switch>Computer's

Dont worry about DHCP it is not required.

I would not use your windows 2003 server as the default gateway for the internet.

You will have to go to each computer and configure on the Ethernet NIC and tell it its default gateway which would be the LAN IP of the router.

Go into the router and turn off DHCP and tell it the LAN IP so it can communicate with the PC's on your LAN. DHCP will still be needed for the WAN port on the router unless your DSL was given a static IP address.

Also let us know what type of e-mail system your using.

Hope this helps.
