despite the igmpproxy software seems to be fixed - no more outputs like:
received packet from 10.66.255.248 shorter (32 bytes) than hdr+data 
length (24+32)

I still can't get it running correctly.

I have several questions:

1- is loading  module ip_mroute  sufficient or DO I need really 
recompile kernel with option MROUTING?
2- does igmpproxy work with if_bridge(4) interfaces (it bridges WiFi 
with cable LAN)
3- is there any other software I could try?
4- how could I debug the process of multicast routing between upstream 
and downstream interface?


Cheers
