IPtables allow IGMP packets for IPTV


New Around Here
Hi! I have an AX86U router and I'm trying to set it up so that it allows IGMP packets on the network. At least, i think that is issue. I have added a rule to the "firewall-start" file in the jffs/scripts directory. here is a copy of what is in there right now:


/jffs/scripts/YazFi runnow & # YazFi Guest Networks
sh /jffs/scripts/firewall start skynetloc=/tmp/mnt/wrtdrive/skynet # Skynet

iptables -I INPUT -p igmp -j ACCEPT #IPTV accept igmp packets

I'm assuming the mcpd service is routing all the packets correctly within the network.

I don't see the new rule on the IPtables readout on this command.

iptables -L -nv

Any ideas what is going wrong?

It should appear as protocol 2 using the following command.

iptables -vnL INPUT

igmp is protocol 2. If you run the command again without the -n it'll be more obvious.

iptables -L INPUT

Ah! found it running the iptables -L INPUT command

Chain INPUT (policy ACCEPT)

INPUT_ICMP  icmp --  anywhere             anywhere
logdrop    all  --  anywhere             anywhere

There seems to be a duplicate entry there though, so maybe I can remove it from the script folder?

It still didn't work though. what is happening is that it does load channels, but they drop after about 10-15 seconds.

I'm trying to follow this guide: https://community.ui.com/questions/...ik-TV-IP/42f380eb-4c23-427e-980a-f4755fd2b44d
