Hi, Thanks, but the JVM Option did not solve the problem :-( I tried the telnet session to port to 3873 for the reason, that i do not have problems with the lookup but with the invoking on the proxy. -> Connection refused as the ethereal trace said too. How can i make the server listzen on the public device? Any further ideas? Thx View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4023535#...
