Probably has been asked a hundred times but it is giving me grey hairs.

SuSE 9.3 is connected to the Network via eth0
A 2nd Ethernet card eth1 has been installed which is now hooked up to the Internet via ADSL modem.
Internet works through the eth1 card for the SuSE9.3 PC

Internal Network works through the eth0 card of the SuSE 9.3 PC

I am trying to get the Internal Network to access the Internet through the Linux box with the ADSL modem.

All PC's are set up with fixed IP ranges for the moment for the sake of simplicity.

The internal address range is: 192.168.0.**
The eth1 card on the Linux PC is: 10.0.0.*
The ADSL modem is: 10.0.0.***

Do I use masquerading to get from eth0 to eth1 for the other internal PC's ?
If so how?

Which one is the Gateway that I have to enter into the internal PC's ?

I think you're looking for NAT (network address translation) and masquerading. Try using a gui frontend like fwbuilder or guidedog.

The gateway will be the linux box eth0, which looks like 192.168.0.xxx. Generally the convention is for the router to be 192.168.0.1, but it's really arbitrary.

Search the forums for linux router setup to help out with command line stuff if you can't get a gui to work for you.

Sorry for the very late reply.
Yes it's solved..:-)
Forget about YAST as the explanations for Masquerading/forwarding etc are rubbish.
I used your links and some info that comes with Firewall2 and manually edited the config file.

Go to: /usr/share/doc/packages/SuSEfirewall2/EXAMPLES.html
This is located on your HDD
The above info and those examples will get most people up and running fast.

Thanks again for your help :-)
