First of all make sure your firewall is disabled.

iptables -L -vn

should give something like

Chain INPUT (policy ACCEPT 25323 packets, 21M bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain FORWARD (policy ACCEPT 0 packets, 0 bytes)
 pkts bytes target     prot opt in     out     source               destination

Chain OUTPUT (policy ACCEPT 25294 packets, 4586K bytes)
 pkts bytes target     prot opt in     out     source               destination

Then check whether you have the ports open on your SuSE box with

netstat -lnt
