Hello,

I have a situation whenre the network topology is like
this:

The network topology like this.

Internet---| Redhat GW|------192.168.1.0 network-----|X
Router|----172.16.4.0 network --|Redhat GW that just
forwards traffic|----172.16.3.0 network

Problem is access of internet from 172.16.3.0 network.

I can access the internet from 192.168.1.0 network. I put
the DNS address of Interenet provider in the clients to
access the internet.

While I can access the internet address from 172.16.3.0
using public IP, I cannot access internet from the only
Windows 2000 client in that network using internet
address. When I ping 'www.google.com' it says "unknown
host" or something. The redhat GW is not a DNS or DHCP.

I would appreciate some insights and advices.

Thank You.

Since you seem to have internet connectivity from that network the problem
is dns name resolution. The first thing I would check is that the problem
computer is configured to use the same ISP dns servers as the other
computers that do not experience the problem. Ipconfig /all will display the
configured dns servers and nslookup run on that problem computer can tell if
they are responding and/or resolving internet names from that client. Keep
in mind that W2K caches negative dns queries for a short period of time, so
if you make adjustments try a using a different dns name to resolve or run
ipconfig /flushdns before any new try. --- Steve
