[App_rpt-users] Asterisk and Echolink no direct connected radio

Fri Aug 14 21:51:53 UTC 2009

Thanks James.

Unfortunately this is not the case.  I have verified both UDP ports are sent
from my router to my internal server 192.168.2.110.
I also have run the windows Echolink and ran the test firewall function and
I can verify my ISP does not filter the ports.

The following is a tcpdump of the inbound connection to my Asterisk box on a
connect to verify the conversation makes it to my Asterisk box.

[root at test ~]# tcpdump host  204.13.148.174
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
