Well, you could always download the program (search Google) and try it. The if* commands are scripts that are run, on Mandrake they are in /etc/sysconfig/network-scripts (I believe). Those scripts should invoke some command that get the IP address from the AP. Look into those scripts and you may find another command than dhclient.

That's what happened to me, eth0 worked, but eth1 didn't. I couldn't even ping other computers under that router (possibly due to blocked lo interface). I don't know how SuSE works, but it'll use iptables as the firewall for Linux (if your router has a firewall you shouldn't have to run one in Linux - I believe).

There are interfaces to configure iptables, such as Shorewall and Guarddog. If you want to remove the firewall, do the following:
	iptables --flush
	iptables --delete-chain

If you can connect to the internet after this, you probably have a firewall-configuration issue. AFAIK: if you don't have a firewall and your card has an IP address, then you should have connectivity.

Honestly, I don't really know anything about Linux and its configuration possibilities... But I'm an happy amatuer who likes to experiment - though it can be frustrating when it doesn't work.
