Mi Magnus: Just a couple of ideas; used to run into this from time-to-time. Problem is, each environment is different, so you might have to try a few things to find the root of your error. http://www.jboss.org/wiki/Wiki.jsp?page=UsingJBossBehindAFirewall -Djava.rmi.server.hostname=<external_host_name> | -Djava.rmi.server.useLocalHostname=true I've also needed to set /etc/hosts or C:\Windows\System32\drivers\etc\hosts to include the external host name and set to local IP. And once, I needed Reverse DNS to be properly set up. Let's see what luck this brings you. S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4118775#...
