EchoLink is a peer-to-peer system, by design.  This means that when your node is connected to another node over the Internet, the voice and text signals are sent directly from one node to the other, rather than going through some central server.  This helps ensure that the system is scalable and reliable.

Unfortunately, there are certain situations in which peer-to-peer connections such as these are difficult to establish.  A growing number of Internet providers are offering “one-way” access to the Internet � allowing your computer to initiate a connection, but not to accept one.  These include wireless community networks, or hotspots.  An example is the wireless Internet service now being provided by many hotels to their guests.  Guests with wireless-enabled laptop computers can check their e-mail and surf the Web from their rooms.  The hotel uses a router with a fast Internet connection and a single public address (or a small pool of addresses) shared amongst all guests.  This arrangement does not work with EchoLink, because the guests’ computers are not reachable from the Internet.
