[suse-security] Question regarding WLAN security & FW2

Hello list,

I hope this is the correct ML for my question:
I have an SuSE 9.1 based system, which acts as server for several
Right now there are three NICs (interface eth0, eth1, ath0).
eth0 points to the internal LAN (
eth1 might point to the internet (DSL line)
ath0 points to the wireless LAN (

Several hardware wlan-routers have options to accept/deny access based
on MAC adresses.
And as far as I understood my chances on Linux, I have to do this via
iptables ....

So I checked FW2, and I guess my only chance to install this is by
editing two files:
/etc/sysconfig/SuSEfirewall2 &
Is that correct??

Next point is:
how does I have to configure it correctly?
I hope its not totaly wrong this way:
    FW_DEV_INT="eth0 ath0"
    iptables -A FORWARD -m mac --mac-source 00:01:02:03:04:05 -j ACCEPT

I didn't activate it till now, as I'm not sure if it'll work ... or how
it has to look like.

Could you give me a hand? Or some advise?

Thanks in advance!
