Allow IPTV IGMP traffic on wan/lan networks

JaymilBhudia

How do I allow IGMP snooping on XG Firewall for BT Vision to view internet channels.

    It looks like BT Youview needs the settings below

    Obvioulsy I enabled the IGMP proxy,

     

    then after the broadband etc was all configured/working, I checked the advanced routing table and there was a route to a subnet configured on the WAN (nothing i had confgiured, also showed my lan 192.168/16 subnet). the table had a default route 0.0.0.0/0 gw 172.16.15.25. and route of 172.16.15.0/24 gw default.

     

    I then configured the "secondary internet" connection (first tried dynamic IP - didn't work). Then tried an static IP address picked randomly within 172.16.15.0/24 subnet - for me i used 172.16.15.24/24. Then suddenly the IPTV channel suddenly kicked into life.

     

    So the key seemed - normal IGMP proxy enabled as normal, plus the secondary connection configured with static IP using a IP from the rogue subnet found in the routing table.

     Does any one understand this and how can this be implanted on Sophos XG?

     

    I can't fully explain how/why this makes it work but it seems to be key to getting it work - disable it and breaks again. Maybe a BT IPTV technical guy may be able to shed some light to the 172.16.15.0/24 subnet which appears on the WAN interface. My working theory the secondary interface creates a link/bridge between lan network and IPTV LAN.

    Hi Jaymil

    Any chance you can get me a screen shot of your interface settings?

    I am PPPoE Dialing to BT via a BT Openreach modem and change the preferred IP to a random one in the same subnet as the gateway IP it pulls

    Here are my Interfaces

    Also, how did you enabled the IGMP proxy!?!

    Thanks in advance

    Hi,

    I have not been able to implement it on Sophos yet but the extract I qouted is from BT forums where people have got it to work with TP-Link routers, 

    I dont know if we are allowed to post other web links on this forum therefore I did not include the link to the BT forums where I got the infomation from.
