BT Youview plays for a few minutes then stops

[stred]

@stephenw10 no its not plug and play, the configuration steps are very similar between the three platforms.

create a new network interface and bind it to the same interface as the dsl modem, create the forwarding rules in the firewall and the igmpproxy config.

Ah, OK.

So if it stops like that either the state closed in which case I would expect to see traffic still arriving and blocked in the firewall log. Or the client unsubscribed from the multicast group for some reason.

Try starting the igmpproxy from the command line to get debug output from it. Stop the igmpproxy service in the gui then run:

igmpproxy -d -vvvv /tmp/igmpproxy.conf

You should see something happening when it stops streaming.

I had to reinstall pfsense and use a backup config, something didn't quote go as I expected though, the youview doesnt work at all now, i disabled the service from the ui and when running the shell command I get....

login-to-view

Almost appears as though the service isn't there at all even though it appears on the services menu.

i'll restart from scratch later this week, family are fed up with me tinkering now!

cheers

Like the conf file has not been created at least....

@stephenw10

so i've got back to where I was by resetting to default config and starting fresh and adding everything back in.

I needed to use

login-to-view

I tried to watch the output for any obvious errors at the point the picture dropped out, but didnt really notice anything.

[stephenw10]

Ah, sorry, yeah my error. Copy/pasted the wrong thing.

So if it does not show a multicast stream unsubscribing does it show traffic blocked in the firewall log?

[stred]

@stephenw10

heh no worries!

Here are some logs at the closest moments I could get.

Firewall

login-to-view

tbh, i'm not really sure what i'm looking for aside from the multicast addresses, the youview box ip is 192.168.1.80 but i don't see that anywhere, the only local address is 192.168.1.102 which is my sons pc, the 10.10.10.10 is the ip address i gave the IPTV interface.

What firewall rules do you have on IPTV? Assuming that's the PPPoE parent interface?

What rule does it show is blocking that if you click the red X?

@stephenw10

IPTV is assigned to the same interface as the pppoe connection, firewalls are here

login-to-view

This is from this morning when I first switched the youview on box on, I don't know what state it was in, but it matches the group of similar logs from yesterday.

I appreciate your help on this issue thus far.

[stred]

ok, so it seems i've made good progress and i've been watching drop out free for a good 15 minutes.

I studied the openwrt firewall rules and noted a couple of differences in particular there was no specified port on the IPTV interface so I removed that and also added this.

login-to-view

After some testing disabling this rule causes the drop out issues, i'll need to do further testing on the assumption I may have opened something I shouldnt have done and would definitely appreciate some advice on that front.

thanks

Yes, you can see it was blocking IGMP traffic on the IPTV interface so adding that floating rule will pass it.

You don't need to pass all IGMP traffic on every interface though. I wouldn't expect to need it on WAN at all. You don't need 'any' destination there either. It's always better to pass only the traffic you need.

Still seems odd that it appears to be using the source IP of the interface it's arriving at....
