NIC Issue

[pritska]

I setup a W2K server just to learn how things work. When setting it up the only NIC I had was a 802.11B Wireless Card!

I now have an ethernet NIC that I can use on the server box.

I changed the IP address of the wireless NIC to dhcp so that it would just pick up an IP from the router. It did.

I then removed the wireless NIC and installed the wired/ethernet NIC, and gave it the IP address that was formerly used by the wireless NIC.

It accepts the IP no problem, but doesn't have internet access! It can ping the router, but it cannot ping the outside world. If I change it to another fixed IP on my range, it works, but the problem with doing that is all my DNS settings are configured for that particular IP address.

Why doesn't the new NIC work with the IP address of the old NIC, which I released?

This is prob a stupid question but the default gateway on your new wired NIC is set to the IP address of your router????????

yes. as I said, I can ping the router, but not the outside world. I do not have NAT enabled on the router in case someone thinks of that
I am using fully qualified public IP addresses for the server and the router.

I would imagine that the router might have the old wireless/new wired IP you are trying to use mapped to the physical MAC of the wireless card.

Check the routing table/LAT table on the router for this.

DNS problem?!?!?!? Are you pinging an external IP address or just pinging a host name???? Try pinging 4.2.2.2 from the server.

Other thoughts if your assigning static IP address to your server then you could disable dhcp on the router and see if that helps.

What IP address are you giving your server???

i have tried pinging both

http://www.externaldomain.com

as well as an IP address (195.82.x.x).

Neither replies with the wired NIC using the x.x.x130 ip address.

I have a range of 8 IPs from my ISP, which start at x.x.129.

The router's LAN side IP is 129, the server 130, and the rest for DHCP. I don't use DHCP from the server for my client machines, and I also don't log onto domain, as it's on a wireless card so is extremely slow.
