For those using 2.2 Beta, there is a bug that prevents this from working. This interface is on igb0 and has VLAN tag 4 assigned. Let’s get the IPTV interface on pfSense up and running! I have named the IPTV WAN interface WAN_IPTV. That is the way pfSense is naming the interfaces combined with the VLAN tag.
As you can see my WAN is coming in on igb0.6 with PPPoE.
