Regression with igmpproxy

TeeConnector · Apr 6, 2016, 6:33 PM

igmpproxy does not start anymore with a working config from 2.2.6

config:

##------------------------------------------------------
## Enable Quickleave mode (Sends Leave instantly)
##------------------------------------------------------
quickleave
phyint bge0_vlan8 upstream ratelimit 0 threshold 1
altnet 193.158.132.189/32

altnet 217.237.158.0/24

phyint igb0 downstream ratelimit 0 threshold 1
altnet 10.0.15.0/24

phyint pppoe0 disabled
phyint igb1 disabled
phyint bge0 disabled
phyint bridge0 disabled

Starting manually via

igmpproxy -d -vvvv /tmp/igmpproxy.conf

results in

There must be at least 2 Vif's where one is upstream.

After going back to 2.2.6 igmpproxy works again.

As a cross test I extracted igmpproxy from the 2.2.6 image an tested it within 2.3-RC but this didn't work for me.

Any idea why this IP / Subnet might be found on igb0?

The network for my IPTV receivers (set top boxes) is 192.168.11/24

My main network is 10.0/16.
I wanted igmpproxy to consider only the clients in the subnet 10.0.15/24 where clients could use VLC to initiate streaming.

I wondering more about the bge0 part

Found config for bge0

bge0 is disabled for igmpproxy and bge0_vlan8 is my upstream.

athurdent · Apr 7, 2016, 10:28 AM

Yeah, sorry, forget my question :)

The problem is probably not with your 10.x nets, igmpproxy cannot see bge0_vlan8 it seems. It only recognizes bge0.

TeeConnector · Apr 7, 2016, 10:49 AM

This seems odd as it sees bge0_vlan8 in the config. I suspect a buggy igmpproxy as it does not see the system interface.

Fortunately there is a new home for igmpproxy with a lot of patches included:
https://github.com/pali/igmpproxy/tree/next

Unfortunately I have no dev environment for FreeBSD where I could try to compile it myself.
