can't get from LAN to internet

[Guest]

I have just rebuilt a crashed W2K server but can't get the internet connection fixed right. Before the crash, users on the LAN side could access the internet through our firewall router connected to the server's 2nd NIC. Now the LAN works fine to the server, and the server connects to the Internet, but the users are unable to get through. The server is configured to act as a DMS/DHCP server providing the users with an IP address in the internal net range. The internet connection is a static DSL connection and the router is configured to act as the gateway for the server through the 2nd NIC card. What do I need to do to enable the users on the LAN to get through to the internet?

 

[Marina Roos]

Do you have options 003, 006 and 015 in DHCP-server, Scope options? Have you
checked the bindingorder of your nics and made sure the internal nic is on
top (Network Connections, Advanced, Advanced)?
DNS on your servernics should *only* point to the server-IP.
Can you post the ipconfig/all from the server?

In addition to Marina's comments, use regedit and go to:

HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Services\Tcpip\Parameters

Set IPEnableRouter to a value of 1

Also, make sure the default gateway address you are pumping out with DHCP is
the internal NIC IP for the server and that the server's internal NIC does
not have a default gateway configured.

In the DNS console on your server, right click the server and select
properties. On the Forwarders tab, make sure you have enabled forwarders
and entered these addresses: 206.13.29.12, 206.13.30.12

You should remove these addresses from your Lan NIC configuration.

Control Panel, Network Connections, Advanced, Advanced.
DNS on the nic is not good. It should point to your server-IP only.
You put the ISP-DNS-numbers in the tab Forwarders of DNS-server.

Thanks for the suggestions, but some don't work. Can't enable forwarders because its a root server. I did remove the other DNS addresses from the NIC l\LAN configuration. Got the binding order changed so the LAN is first and the WAN second.
I set the IPEnableRouter value to 1. Do I need to reboot for any of these changes to take effect? If not, no change in the problem. If so, I'll have to wait until everyone goes home so I can take down the server. Thanks.

In order to enable forwarders, remove the forward lookup zone called "."

We're getting close! Trying to connect from a LAN station to MSN.com, the name resolves to the IP address, but apparently times out. Tried Yahoo with same result: resolved to and showed the IP address, then after a period of time put up the "this page cannot e displayed" error message.
Kearney Tried changing the time out setting from 5 seconds to 30 seconds, but no joy.

 

[Marina Roos]

Did you remove the "." zone in DNS-server, like Doug suggested? Does DNS on
both nics point to the server-IP *only*? On the external nic, is only TCP/IP
bound? Have you restarted DHCP-server and DNS-server?
Can you post the ipconfig/all from the server please?

Deleted the "." zone but did not remove the DNS servers from the WAN NIC. Can't restart everything until the staff all goes home. Will clear the cache on ie on the workstation and reboot everything in the morning before the staff gets in. Meanwhile, here is the ipconfig/all info:

Status report: still can't get through from workstations.

Changed DNS server setting on WAN NIC to same as on LAN NIC (10.0.0.150), Restarted server. Cleared temp files and history from IE. Still attempted to connect showing the IP address of the target site rather than the name but timed out to the "The page cannot be displayed error message."

Next, I hooked into the net a Mac Tibook and had it check network configuration. It got its individual IP address from the DHCP server, showed the 10.0.0.150 gateway address and listed the router at 192.168.0.1. Still unable to complete a connection.

Do you have options 003, 006 and 015 set in DHCP-server, Scope options? 003
should point to your server-IP.
