igmpproxy + iptv

Доброго. Возникла проблема: решил настроить ретрансляцию iptv во внутреннюю сеть.
Имеется интерфейс в сеть eth0 (192.167.1.1)
и в интернет eth1 (192.168.15.18).
Подсеть с iptv 233.163.114.*

конфиг igmpproxy:
quickleave

phyint eth1 upstream ratelimit 0 threshold 1
altnet 233.163.114.0/24
altnet 77.0.0.0/8

phyint eth0 downstream ratelimit 0 threshold 1
phyint eth2 disabled

конфиг iptables:
iptables -I FORWARD -d 192.167.1.0/24 -j ACCEPT
iptables -A FORWARD -p udp -m udp -j ACCEPT

но при запуске $igmpproxy -d он пишет следующие:

и поток не ретранслируется. В чём может быть дело?
