That's because for security reasons, applets (unless digitally signed) only allow connections to be made back to the exact same host (including exact IP address) that the applet was downloaded from.

You're in for a world of similar issues if you're going to be trying to deploy applets that need to talk over the network on any protocol other than HTTP.

Maybe if you posted what you're trying to accomplish, we could give you some ideas on how to make it work?
