ah. ok !
then all you need to do on your suse 9.2 machine
is to set up the network card with yast as indicated in the pictures
I posted earlier. I assume that it was/wil be detected automatically. everywhere it says sth like "get yadda yadda via DHCP" just enable that stuff. like "get iP address automatically", "get nameserver automatically", "get hostname automatically" ...
it might be necessary to add the router's IP address (manual) as the "default gateway" of the linux machine.
no need to configure the dhcp server on that computer.
If the netgear router is still in factory default configuration its dhcp server should be turned on by default. the next time you reboot your linux computer ( or restart the network with "/etc/init.d/network restart" ) it should get an IP address from your netgear box. as soon as that is done you must be able
to ping the router.
THEN I assume the manual says something about the netgear's default IP address and the WEB interface password.
it should be accessible with any browser via
http://router.ip.goes.here
then comes the part of configuring the DSL dialup stuff.
but that should be straight forward. just username, password, type of connection ( usually pppoe ).
if that's done you should be able to surf the internet from your pc.
firewall should be enabled as well. preferably on the router.
