Configuring firewall for MythTV

Post #1 of 4 (410 views)

I just upgraded to 31-fixes, I'm noticing that everytime my frontend hits
the tuners on my secondary backend that the backend service drops. I'm
suspecting my Verizon FIOS router. How do I open router ports for internal
traffic, but not the Internet? No real documentation for this router, it is
a MI424WR.

Thanks in advance.

The MythTV boxes should all be set up on the same Ethernet subnet, so
their traffic should not be going through the router.

Documentation for your router is in fact available here:

I had a router some time back that would drop packets. I solved it by
using a switch for the internal traffic and only used one port from the
router, which connected to the switch, and the switch connected to the
other devices. However the problem it caused was pixellated recordings,
not a backend crashing. So I suspect some other issue in your case.
