Re: Linux gateway - multicast problem

[Karsten Siebert <Karsten.Siebert@dataplanet.net>]

Have a look at your /etc/mrouted.conf and verify the following entries.

phyint dvb0 altnet 128.0.0.0/1 altnet 125.0.0.0/1
phyint eth0

Did you enable PID 0x312 (tcpdump shows only PID 0x311, check for x.x.3.18)
? Otherwise let dvbd do it for you (if you set dvbauto to ON and disable the
PID in /etc/dvbd.conf (#).
