Model: ER605 (TL-R605)  
Hardware Version: V2
Firmware Version: 2.0.0 Build 20220106 Rel.56391

Hi,

I have recently installed an ER605 to replace my BT HomeHub and it is working well on my BT FTTP connection.

 

However, the IGMP Proxy service does not appear to be working at all. The BTTV IPTV channels on my YouView box show in the Guide but cannot be accessed. They time out with a BT error (IPC6023) which basically says to reboot the BT Router. Of course it is impossible to get support for a third-party router from BT, although I am sure their TV service does use IGMP Multicast protocol.

 

The IGMP Proxy is enabled in the  Network | Lan page and I have tried both V2 and V3 versions.

 

Is anyone using this router successfully with IGMP?

Thanks

I have now updated the ER605 to the latest firmware (2.0.1 Build 20220223 Rel.68551) but with no success :-(

 

All the threads related to the use of third-party routers to access BT TV in the BT Forums have been locked so only BT employees can access them. 

Anybody successfully using an ER605 to access BT TV?

Thanks

An update for anyone trying to get an ER605 to view BTTV IPTV channels, my problem was NOT the IGMP Proxy.

 

BT use a PPoE connection over FTTP and that works fine on the ER605. However, the IPTV streams are broadcast via PIM so are not picked up by the PPoE connection.

I solved it by adding a secondary connection to the WAN definition, I gave it an RFC1918 (non-routable) address. The ER605 was smart enough to automatically add a Route from the IP address of the secondary connection across onto the LAN side.

This second connection picked up the MultiCast UDP packets so the BT streamed channels (BT Sport etc) work fine.

Of course IGMP is also required to ensure the MultiCast packets don't flood the internal LAN

 

Problem solved!
