Multicast routing, IGMP, IPTV doubts..

[Marek Salwerowicz]

Hi all,

My home router is small FreeBSD 10 box, with 3 ethernet ports, I use pf 
as a firewall.

My ISP provides FTTH, that ends at my home with a small box called CPE. 
The CPE contains 4 ethernet ports. On one port I have Internet access, 
on the other there is IPTV (that's based on udp/multicast)

The IPTV works well - when I connect directly my PC to IPTV ethernet 
socket - I can watch TV.

But I would like to have both Internet and IPTV on my desktop at the 
same time.

I've downloaded the igmpproxy package, set up config:

quickleave
# IPTV interface
phyint re2 upstream  ratelimit 0  threshold 1
    altnet 10.0.0.0/8
    altnet 192.168.0.0/16

# LAN interface , bridge0 as it's re0+wlan0
phyint bridge0 downstream  ratelimit 0  threshold 1

# Internet access interface
phyint re1 disabled

I've also loaded the ip_mroute module into kernel:

10    1 0xffffffff81aa7000 cd91     ip_mroute.ko

And enabled UDP traffic in PF:

IPTV="re2"
int_if="bridge0"

# IPTV
pass in on $IPTV inet proto udp from any to any
pass on {$int_if, $IPTV} proto igmp allow-opts



Unfortunately after starting igmpproxy:

# igmpproxy -d -vv igmpproxy.conf

the igmpproxy starts but can't build routing table:
Current routing table (Age active routes):
-----------------------------------------------------
No routes in table...
-----------------------------------------------------
received packet from 10.66.255.248 shorter (32 bytes) than hdr+data 
length (24+32)
received packet from 10.66.255.248 shorter (32 bytes) than hdr+data 
length (24+32)
received packet from 10.66.255.248 shorter (32 bytes) than hdr+data 
length (24+32)


Do you have any idea how should I configure my box to be able to route 
the IPTV traffic?

Regards,
Marek
