Suse Firewall and Tomcat

Hi; We are using Suse 9.0 and started to use Suse Firewall for our server.But we have a problem. We have two interfaces eth0(external) and eth1(internal),we want use Tomcat server on port 8080.Using Yast Firewall menu I configure the firewall and add port 8080,www,http parameters but we can not connect our server from internet .Also we cannot ping the machine from internet.Internal interface work good we have not any problem about internal interface. Did I made a mistake about configuration.I need to add more parameters? Thanks Murat Akca
