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.

    I have had it working with a TP-Link Router and Pfsense. IGMP Proxy is the key.

    Hi Jaymil,

    You could use the XG as a Proxy for IGMP under System > System Services > Web Proxy but I highly doubt that would work

    But I think you need to actually turn on Multicast forwarding which is done by looking at this guide from Cyberoam (Sachin, may need this one updated for Sophos?): https://kb.cyberoam.com/default.asp?id=1021

    As far as I'm aware the XG is not an IGMP proxy (yet) but you can forward it to the appropriate place using that guide. Maybe that's what is needed to make Sachin's original suggestion work?

    You will need to find out what the IGMP source is however from BT.

    Hope this helps,

    Emile

    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.

    Not sure why that would work!  But I will definitely give it a go tonight on my connection and let you know how I get on.

    I tried using another router (Draytek and Sonicwall) works fine so a BT Homehub definitely is not required for the IPTV to work.

    Did you have to create any specific inbound/outbound firewall rules/app rules/web filter rules?

    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.

    Has anyone managed to get this to work with Sophos XG yet?

    Hi Jaymil,

    I would like to learn how IPTV works and if it is required to configure the multicast routing on the firewall. Please refer, How to Configure Multicast Routing in Sophos Firewall and loop IPTV support for the solution.

    Thank You,
