Hi,
I have setup a LAMP server (Ubuntu server 7.04) with the below ip services and applications. My LAMP server is able to distribute ip address to the clients and able to connect to the internet. However, all the clients are unable to connect to the internet. Please advise on how the server is able to share out the internet connection. Thanks.


I have these installed :-
(1) DHCP
(2) DNS

Depends how the clients are connected to the server and how the server is connected to the internet.

Typically, one uses the firewall script to share an internet connection with a network.

Presumably, the server serves IP's for the LAN (with, maybe, caching DNS otherwise). LAN hosts thus connect via a switch or a hub, by DHCP. You need to set up the server as an internet gateway.

Have a look at the links in:
http://www.linuxquestions.org/questi...88#post2806588
... covers making an internet gateway with NAT and masquerade.

An alternate approach involves "bridging" but I don't know if that is the right approach for you.

Install the firestarter application in Ubuntu, it will make it really easy for you to setup firewall/routing for your internal clients.
