I'm trying to get an hdhomerun set up and my firewall is getting in the way.

After stracing the hdhomerun_config binary and seeing that the discover calls out on the network broadcast (192.168.0.255 here) on port 65001 I did some tcpdumping (also knowing my hdhomerun was at 192.168.0.16 and I'm at 192.168.0.15):

So I can see that the hdhomerun is responding, but from random ports.

So poking a hole in my firewall for responses from 192.168.0.0/24 (in case I have m udp source port 65001 I can communicate with this.  Now I'll have to see how streaming works once I get it added to MythTV.
