IPTV IGMP multicast problems with BT YouView on pfSense

[casualsix]

I take it you've got DHCP server and "DHCP" firewalls rules setup for the BTVision Vlan?

[casualsix]

The error message is to do with the IGMP multicast not working, not due to the Youview Box not getting internet. I would recommend deleting your out nat rules to keep things simpler, unless there's another need for them.

You could try this…

Under System -> Advanced -> System Tunables, add a new entry with the Tunable as "net.link.ether.inet.allow_multicast" and the Value as "1".

casualsix,

Thank you for the pointers. I have removed all outbound NAT rules for 192.168.0.0/24 WAN,BT_VLAN,EXTERNAL_BT :).

I have also added the tunable you supplied.

For good measure I rebooted everything (PfSense, BT box) but sadly I now receive that the box can't see any broadband connection. This error seems to go away with the NAT rules.

Regarding the BT Vision VLAN: I've attached a screenshot of the rules, yes it has a DHCP server :).

As always thank you for taking the time to assist!

Also, in your "BT Vision vlan" firewall rule, wildcard "any" the source, Instead of the strict rule.

Casualsix,

Thank you so much for sending this over. Sadly even with a colleagues help and using your rules as templates we couldn't get it working. I must be missing something, not sure what though.

May I ask what kind of IP range you are using on your WAN? I'm using 10.20.30.1/24

[casualsix]

For my secondary IPTV WAN i'm using a 10.10.10.1, IGMP Proxy isn't really fussy about what you use.

I'm using a EchoLife HG612  (BT openreach) "firmware hacked" ;D  modem, is that what you have?

When you turn off you outbound nat rules , I take it your youview box is seeing the DHCP O.K.?

I also read somewhere that BT need the Youview DNS to be pointed at they're servers but Im not sure if thats true, but it's not the case with Plusnet supplied youview service though (Obviously part of BT anyway)

[casualsix]

Also, For Info,,,,,,I've tested your IPTV WAN IP 10.20.30.1/24 , and it's working fine with my setup.

[Jimbo]

casualsix,

Thank you for testing my IPTV WAN IP and confirming I'm not going mad haha!

Yes I have a EchoLife HG612 but the firmware isn't hacked. Do you think that could be the issue?

I'll try BT DNS later today - At this point I'm grabbing at straws :)

[casualsix]

No, the standard BT Modem works fine also. Have you considered the SG-2220? Its such a improvement, I've messed with VM's and Iso installs but found Netgate hardware the answer for me. No IGMP Proxy issues and internet and VPN features I used are great,

[Jimbo]

casualsix,

Thank you, at least I know that the modem unit should be fine. I might try to install PfSense on metal to see if KVM/QEMU is doing something weird. I will take a look at SG-2220 and see what I think. I kinda like building my own stuff but then again these problems happen!

I do appreciate all your help. I have promised the other half that if I can't fix this we may go to another TV service that doesn't reply on IPTV :-).

[casualsix]

OK not problem, If I had a standalone linux o/s to install QEMU i'd test pfsense for you out of interest. I too like to try thing out but IGMP proxy got the better of me and forced me to get the Netgate hardware.

Hi Jimbo,

Just wondered if you ever made any progress, I am using a VMware VM and also unable to get it to work.
