Routing Problems

[Simon21]

Hi,
I have a windows.net server and try to NAT my internet connection to my clients. (I have 2 NICs on my server)

The clients can ping the network card attach to the internet but cant see web pages. When you entre google.com, the browser find the appropriate IP, so it is not a DNS problem.

I think it must be a routing problem because I cant ping (from clients) the router behing the second NIC on my server.

Anyone can help?

firstly: try NSLOOKUP on a client. type in an IP address and see what server answers your queries.
If you cannot send a signal to the internet, you cannot contact a DNS server directly either.
Your gateway machine might not have that problem though (being directly connected), allowing it to resolve queries for your internal machines despite the fault.

Can you use the .NET server to browse and ping? Is there any firewall inplace that might be blocking the packets path?

I think you might have to add a default route to your internal machines.

Typre 'route print' and see if you have a default gateway. (destination 0.0.0.0) If not you'll need to add a default route.
