Echolink not connecting

When you ran the Echolink Setup Wizard, did the UDP (5198-5199) and TCP
(5200) ports show as open? I'm guessing no. You probably will have to
open the ports in your modem/router.

Echolink operates by sending and receiving packets of data through the ports
as opposed to using standard ports, for example port 80. These ports are
blocked by a router or a modem that has router function. So, the router
assigns a local IP to your computer. To ensure that the same IP is assigned
to your computer every time you boot it up, you need to configure the router
to recognize your computer. Then you configure the router to open the ports
for that particular IP. This process is called "port forwarding" and you
can go to www.portforward.com , look up your router and set it accordingly.

Cable modems typically shine the ISP assigned IP through and Echolink will
work after you make exceptions for Echolink in your operating system. ADSL
modems usually require configuration. In my case, I have configured the
modem to stop acting as a router (DHCP) so that it passes the ISP assigned
IP to the router, which is configured to open the required ports for a
locally assigned IP.

Like drinking from a firehose, no?
