Is there anything like an ADSL router or an ISDN router between you and the Internet? Exactly what these devices do differs between manufacturers, models, and firmware revisions, but there are some common traits: * They'll usually be configurable through a Web browser. They'll very often have telnet access, and quite often have ftp access (for uploading firmware). * These ports will always be open on the LAN side. Sometimes, they'll come by default with these ports open to the Internet. * If they have ports open to the Internet, they'll often handle those ports themselves, and pass any other incoming traffic back to a specified computer on the LAN side. (Often, they'll stretch terminology and call this the "DMZ host"). This is especially common where the device has only 1 public IP address and does NATting. Usually, you can turn all this off. If you can't find what's providing these services on your PC, look at your network connection.
