i am trying to make a chat (using an applet for the client).......
it uses an simple socket connection between the server and clients.....when i connect the client to address 127.0.0.1 or localhost everything works fine, but when i try to connect the client to my DNS name or ip, i get an exception....the exception reads:

java.security.AccessControlException: access denied (java.net.SocketPermission nextwave.dyndns.org resolve)
