What kind of error are you getting? Stack trace?
"0.0.0.0" will bind to "all available addresses" ... if your remote host is resolving this to "localhost", or "127.0.0.1", then that value will be in the remote proxy returned, and your client will try to contact itself. If you're running Linux on your remote host, you can resolve this by editing /etc/hosts to point localhost to "10.1.18.25". This error should manifest itself as an NoSuchObject error or a ConnectException...
Or maybe you're just looking up the wrong address in JNDI? Ensure it's "Conecta", and not "Conecta/remote" or similar by checking the JNDI Tree: http://wiki.jboss.org/wiki/Wiki.jsp?page=DisplayTheJDNITreeWithTheJMXConsole
Good luck. :)
