Can i use igmpproxy on tunnel interface?

Installing and Using OpenWrt Network and Wireless Configuration

Hello

I wonder if i can use igmpproxy on tunnel interface?
I have some DLNA client on the other side of the network.

I would like to have a following setup:

R1 config:

config igmpproxy
        option quickleave 1
        option verbose 3 #[0-3](none, minimal[default], more, maximum)

config phyint
        # DLNA server
        option network lan
        option direction upstream
        list altnet 0.0.0.0/0

config phyint
        # client side
        option network tun0
        option direction downstream

R2 config:

config igmpproxy
        option quickleave 1
        option verbose 3 #[0-3](none, minimal[default], more, maximum)

config phyint
        # DLNA server
        option network tun0
        option direction upstream
        list altnet 0.0.0.0/0

config phyint
        # client side
        option network lan
        option direction downstream

I also try to include in a lan side:

             option igmp_snooping 1

What i see:

1. If the upstream side is the tunnel interface there is no any log from igmpproxy. I assume it is hung

2 if i restart the network in R1 side the network the tunnel interface cannot come up it is blocked by igmpproxy. (if i stop it it came up)

3. In the logs in R1 i just see this:

So long as the tunnel is Layer 2 or handles broadcast packets, yes..

How does IGMP relate to DLNA?
