hi everybody, i'm a newbie here and also to linux. i installed SLES 9 to my server and would like to make it as a router/internet gateway to my workstations. here is the details :

server :
os : novell suse linux enterprise server 9
eth0 ip : 10.0.0.1 subnet : 255.255.255.0 (connected to switch)
eth1 ip : 192.168.0.2 subnet : 255.255.255.0 (connected to adsl router)

adsl router :
ip : 192.168.0.1
subnet : 255.255.255.0
dns : 202.188.0.133, 202.188.1.5

workstations :
os : windows xp & novell linux desktop (dual-boot)
ip : 10.0.0.2 onwards subnet : 255.255.255.0

what should i do/configure and how to do that?

regards;

You need to firstly install ip-masquerading and then setup a small script to do forwarding at boot up. There should be any number of howto's on this for your distro on the net ( Google search ). Then you need to configure you networks. The gateway for the Linux box is 192.168.0.1 and the gateway for the boxes on the lan will be 10.0.0.1. All the boxes on the lan must be on this subnet (10.0.0.X). Ideally you should install a firewall to protect the network. A very good all in one solution is provided by MonMotha's script . This is what I use on my system.

i don't know how to do ip-masquerading, neither do scripting. who can help me, please

Sorry mate, but that's what Google is for. You need to install the ip-masquerading package. If you used Debian I could help. If you can't find what you are looking for with Google then post a request in the Distro specific section under Suse.
