This page will describe how to configure Tvheadend to receive multicast TV streams via your Telia broadband connection, note that you must be subscribed to the TV service or else the service is not provisioned to your customer port.

Telia seams to only support IGMP version 2 and default Linux tries to use version 3 with some fallback heuristics that seams to not work that well with Telia. You can force IGMP version 2 by changing the {{{force_igmp_version}}} file in the proc filesystem

If the default route is not routed out on the interface used to receive the multicast stream you must disable [http://www.wlug.org.nz/ReversePathFiltering RPF] or add a route to the source IP used in the received stream otherwise the packets will be dropped by the kernel because of RPF and will not be passed on to Tvheadend.

It is imported to change both of them, if {{{all/rp_filter}}} is 1 the interface specific configuration is ignored

If you instead want to have RPF enabled you can add a route to the source of the multicast stream
