Title: IGMP Proxy with VLAN
Post by: fegauthier on September 27, 2019, 07:12:03 AM
Hi guys!

I want to use IGMP Proxy with a VLAN upstream. I saw many patches for the old version of OpnSense. Does anybody know what I need to do to get IGMP Proxy work with VLAN ?

I'm using OpnSense 19.7.4_1-amd64 with OS IGMP Proxy 1.4

Thanks!

Hi there,

I remember FreeBSD needed a patch or two to compile. As for the VLAN they work out of the box and what happened over the years with the "broken VLAN" issue was that IGMP Proxy is only registering a fixed number of interfaces (I think 40), but if you had more VLANs it would maybe not see your VLANs that you wanted to use because it registered all the others you didn't need.

We bumped the number to 100 and created a preliminary IGMP Proxy pull request, but it was never merged because the maintainer wanted a "proper" fix and wasn't interested in taking up the challenge.

Hi Franco!

I want to let you know that I only have two VLANs 35 and 36. There is my IGMP Proxy configuration.

This is the errors log that I get

Do you think if I'm changing the value 40 to 100 it will work? Can you explain me a little how can I compile igmpproxy and put it in OpnSense?

Thanks!

Finally, it was a problem of firewall rules. IGMP Proxy works great.

Hi there,

Oh, yes, never seen that error so I would have hoped it was something else. Glad you figured it out. :)

Hi Franco!

I have another question for you. My IGMP is link with VLAN (Upstream) and IPTV (OPT1) (Downstream). If one of the two link turn down for whatever reason, IGMP Proxy stop working and never restart. So I have to restart IGMP Proxy my self. Is there any way to start IGMP Proxy when VLAN or OPT1 comes UP ?

Thank you
