Thank you. I admit I have a hard time understanding the "UsingJBossBehindAFirewall" wiki. It refers to services, which I know little about (users guide is too much for my head). Do I need "RmiPort" (1098)? Do I need jrmpInvoker or pooledInvoker (4444/4445), or both? I don't have a clue. Do these ports need to be open on the client side? Do they have inbound or outbound traffic on both sides? About these issues I could not find information I could understand. :( View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4045539#...
