Hard to say what the issues are without more details. Please read the links above and provide more background on the problem. Could be a problem with NAT and IP forwarding/masquerading, or with the DNS setup on the client. You don't say how the IP addresses and DNS for the LAN are being assigned, nor even what operating system is on the client. Presumably, based on the forum you posted in you are using CentOS 4 (4.8?) on the server. Are you running a DHCP server?
