Ok, then that suggests that you don't have your router configured  
correctly.  Echolink uses a new protocol that can route through many  
routers, even with they are not configured to forward incoming  
traffic on ports 5198 and 5199 to the computer.  In EchoMac 1.16.1 I  
added a feature that does the same for connections that you  
originate, but the protocol for allowing incoming connections through  
an unconfigured router are undocumented (and nobody has reverse  
engineered it yet).

So given your current results, it sounds like your router is not  
configured to forward UDP traffic on ports 5198 and 5199 to your  
Mac.  (Note that some cable "modems" also do network address  
translation.  And a tiny number of ISPs only provide private IP  
addresses, not public ones.)  UDP traffic on ports 5198 and 5199 on  
your globally routable IP address must be forwarded to your Mac for  
complete functionality.
