IGMPv3 (igmpproxy) / Telekom MagentaTV / TP-Link Archer C2600

[Ultrazauberer]

Hello together,

first thank you for that great OpenWRT project! After some years I can finally switch back to OpenWRT.

I'm using a TP-Link C2600 V1.1 with the latest stable release (18.06.2). I installed igmpproxy and tried to get my Telekom Mediareceiver to work. The IPTV stream stops working after 10 seconds and begin to stutter. Some seconds after the complete stream stops. A non working IGMPv3 is the problem as far as I know. The stream stops when the Media Receiver is switching from unicast to multicast.

At the moment I don't know a good way to debug my configs. Maybe someone of you can help me?

Here are some of my current configs:

root@OpenWrt:~# cat /etc/config/network

        option ifname 'lo'
        option proto 'static'
        option ipaddr '127.0.0.1'

I'm using just one port (WAN) on the router which is connected to a managed switch and than to the VDSL2-modem. That's why I have VLAN7 tagged and untagged traffic on the WAN port configured.

Thanks in advance!

Why does your /etc/config/igmpproxy differ from /etc/igmpproxy.conf

[Ultrazauberer]

Hmm, good question. I only modified the /etc/igmpproxy.conf and left the /etc/config/igmpproxy as default. So both configs should look similar?

@Ultrazauberer

I only modified the /etc/igmpproxy.conf and left the /etc/config/igmpproxy as default.

You modified the wrong file.

You edit /etc/config/igmpproxy

Thank you so much! Now my igmpproxy configs are looking like that:

root@OpenWrt:~# cat /etc/igmpproxy.conf
quickleave

phyint pppoe-wan upstream ratelimit 0 threshold 1
        altnet 192.168.1.0/24
###     altnet 87.128.0.0/11
###     altnet 224.0.0.0/4
###     altnet 193.158.0.0/15
###     altnet 239.35.0.0/16

phyint br-lan downstream ratelimit 0 threshold 1
###     altnet 192.168.1.0/24

root@OpenWrt:~# cat /etc/config/igmpproxy
config igmpproxy
        option quickleave 1
#       option verbose [0-3](none, minimal[default], more, maximum)

config phyint
        option network wan
        option zone wan
        option direction upstream
###     list altnet 192.168.1.0/24
        list altnet 87.128.0.0/11
        list altnet 224.0.0.0/4
        list altnet 193.158.0.0/15
        list altnet 239.35.0.0/16

config phyint
        option network lan
        option zone lan
        option direction downstream
        list altnet 192.168.1.0/24

Now the IPTV streams are not hanging anymore! Thanks!
