[mythtv-users] backend on multiple networks

[Preston Crow]

When I configure the backend in mythtv-setup, I need to configure an IP 
address, and it uses that to determine which interface to bind to when 
opening the ports.  From a security standpoint, this is good, as you 
don't want to accidentally put these ports out where anyone on the 
Internet can connect to your backend.  However, I don't see how to tell 
it to bind to multiple devices.

In my setup, I would much rather have it listen on all networks and rely 
on iptables to block the untrusted ones.  I have a separate wired lan 
and (secure) wireless network.  I also create ssh tunnel tun devices 
when I connect in remotely (probably not good enough for watching TV, 
but I can show off the interface.).  So some network devices might not 
even exist when myth start.

Another option would be some sort of iptables masquerading to intercept 
connections from other networks on these ports and make them look like 
local connections, but I'm not sure how to go about that.

I've tried leaving the IP address blank and using 0.0.0.0, and neither 
worked.
