Hi. I installed DNS(for local users) and NAT so that our users can get private IP's. We have several "subnets" for NAT set up as seconadary IP's on the LAN NIC. We have a number of servers on the same network with public IP's. Problem is that the users on private IP's can't see the Internet. They all have static IP's. The machines on public IP's can get on the Net with no problem. I was playing around with the Subnet masks and could get all the machines to see each other at least. But they cant even see the webserver that is on site and in DNS on a public IP.What can be the issue? TX.

Try to get into the BIOS too. If the CPU/bus speed is incorrectly set, this can cause the system to not POST or boot.

Wrong post, Curt R? ;) ThatOtherGuy, what do you mean by "see" the Internet? Can the computers not resolve addresses? That would be a DNS issue. Can they correctly resolve addresses, but can't reach external hosts - something you could test with ping or traceroute? That would likely be a routing issue. I'm guessing this is a simple DNS issue. Based on how you described your network, you would have had to configured DNS forwarding (correctly!) on the server and manually entered DNS server(s) addresses on each client. Have you done that?

DNS is definitely working as the machines using the same DNS server can resolve addresses on the Internet. There are several forwarders setup as well. The problem is getting the machines on the private addresses to resolve Internet addresses. The clients are configured with the DNS. I tried using the public IP on the DNS as well as the private IP's and also tried the NAT gateways which is on the DNS. Thanks.

Oye! Ooops! LOL Yep, right post, wrong topic *sigh* Your problem likely stems from having multiple IP's assigned to a single NIC. Try a separate NIC for each subnet and then use RRAS with NAT enabled to handle the internet access for you. I've never tried to configure multiple subnets on a single NIC and when I've done it the way I stated above, it's worked very nicely.

ThatOtherGuy, your writing is way too vague. What are you saying here: "DNS is definitely working as the machines using the same DNS server can resolve addresses on the Internet" but... "The problem is getting the machines on the private addresses to resolve Internet addresses" Huh? What machines are "using the same DNS server?" And what is the "same DNS server?" Should I read that as, computers with public IP addresses can resolve DNS names while computers with private NATted IP addresses cannot? If that is what you mean, then I still think the issue is with DNS on your private network. If you meant something else...please take a minute to organize your thoughts and restate the problem.

Can you from the dos prompt ping tv.com? C:>ping tv.com goto you DNS box, and you can query the internel and external DNS
