I haven't been following this thread and so my answer without reading may be inappropriate. If so, please kindly disregard. Port 53 is DNS, it's what's used to translate domain names into ip addresses. The IP address 192.168.0.1 is a so-called "unroutable" address, meaning that it can NEVER be a valid address outside of "your own network". Now, "your own network" could be very large, but if there's no computer with a 192.168.0.1 address inside of your connection to your internet service provider, then the line:udp 0 0 10.0.0.2:32826 192.168.0.1:53 ESTABLISHED14720/freeswitchwould seem to indicate that DNS is misconfigured somewhere. If you're on some unix-like machine, please check your /etc/resolv.conf file. Anyone more familiar with freeswitch may know that it does or does not use the system resolver, which I do not know. If it does not use the system resolver, then the above advice makes no sense whatsoever.
