<div dir="ltr">It's FreeSWITCH trying to automatically detect the ${local_ipv4} and ${local_ipv6} values.<div><br></div><div>It does this by attempting to send a packet to an IP it knows will have to go over the Internet and seeing which local IP the packet would leave the machine from.

While playing with freeswitch yesterday, Little Snitch reported<br>
that freeswitch immediately upon launch tries to establish a connection to 82.45.148.209 and 2001:503:ba3e::2:30 on port 4242.<br>
<br>
A whois shows the ipv4 to be from Telewest Broadband in the UK.<br>
<br>
The only port 4242 setting I find is in conf/autoload_configs/event_multicast.conf.xml but for 225.1.1.1.<br>
<br>
Blocking the connection prevents sofia from registering with flowroute so I'm curious what it is. I couldn't find any relevant search results.<br>

Thanks,<br>
