Firewall settings for samba Suse 9.3

Hi guys I have just set up samba on suse 9.3 and can see and access the linux box from the windows xp box no problems at all. However I cant see the windows box from the linux box unless i turn off the firewall on suse. What and where do I have to change in the firewall to allow the windows share to be accessible from suse?
