That = is, it doesn't matter what port you open on your router, traffic will never be routed to it. The simplest thing is to get on a computer known to be external to your public IP address, get to a command prompt (any OS is fine) and type: telnet your-public-IP 8080 If you don't get a response back, your ISP is blocking that port for whatever reason, and you can't do anything about it. That, or your = router is messed up. If port 8080 is available on that external IP, you should see a = response like this: Trying your-public-IP... Connected to your-public-IP. Escape character is '^]'. At that point, even if you can't see characters echoed on the screen, = you can type: GET HTTP/1.1 And you should see a Tomcat error message, in plain text. You can try this using your internal IP from another computer, too, = though we know that works already. In any case, if Tomcat is up on your = internal net, but not external, either your D-Link router is messed up, or your = ISP is blocking that port on your public IP, and probably a whole range of others. If your ISP is blocking that port, you can 1) talk to them and = try to get them to unblock it (good luck!), 2) install a connector like = mod_jk and skip worrying about 8080, or 3) dump Apache and run Tomcat on port = 80.
