Firewall Help

I am trying to set up the firewall is Suse 9 I am used to using iptable in the form of $IPTABLES -A INPUT -p tcp -s x.x.x.0/24 --destination-port ssh -j ACCEPT $IPTABLES -A INPUT -p tcp -s y.y.y.0/24 --destination-port ssh -j ACCEPT $IPTABLES -A INPUT -p tcp --destination-port ssh -j REJECT alllowing only networks x.x.x.x and y.y.y.y to have ssh access and block all others. This worked pretty good under Redhat but can't figure how to do it under Suse Thanks
