Vodafone Siro - EdgeRouter 4 and IPTV

Sooo I decided to get the Edgerouter 4 recently

Have the WAN setup with no issues for Vodafone Siro, but man the IPTV I am struggling with

I have setup IGMPProxy on the edge router but I am still in two minds what the settings should be
I think it should be similar to this:
show protocols igmp-proxy
interface eth2 {
alt-subnet 10.10.2.0/24
role downstream
threshold 1
}
interface pppoe0 {
alt-subnet 0.0.0.0/0
role upstream
threshold 1
}

(Eth2 is direct connection to the arris box from Vodafone - using a DHCP range 10.10.2.0/24)

show ip multicast interfaces
Intf BytesIn PktsIn BytesOut PktsOut Local
eth2 0.00b 0 0.00b 0 10.10.2.1
pppoe0 0.00b 0 0.00b 0 64.43.179.xxx


Now if I a do a tcpdump

sudo tcpdump -i eth2
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth2, link-type EN10MB (Ethernet), capture size 262144 bytes

So I was wondering if I need to alter the alt-subnet for igmp proxy?

Any ideas any one?
