[mythtv-users] HDHomeRun Firewall rules, WAS: Fedora 20 mythtv .27 audio issue

[Nick Campbell]

I thought it was strange that I couldn't get the HDHR to work with the
firewall..  I enabled all the ports, but only disabling firewalld is what
made it work, I was thinking of moving to iptables...   This is very
helpful.

Thanks!
