Running igmpproxy on OpenBSD
-----------------------------

To use igmpproxy on OpenBSD, you will need to configure it by
editing /etc/igmpproxy.conf, and configure the OS for
multicast forwarding:

# echo multicast_router=YES >> /etc/rc.conf.local
# echo net.inet.ip.mforwarding=1 >> /etc/sysctl.conf

and restart. Note that client machines using OpenBSD should
be configured with multicast_host=YES.

To have igmpproxy start at boot time, add this to /etc/rc.local:

if [ -x /usr/local/sbin/igmpproxy ]; then
        echo -n ' igmpproxy';   /usr/local/sbin/igmpproxy
fi

PF must be configured so that control packets (proto igmp) and
data packets (destination address within 224.0.0.0/4) are passed.

igmpproxy is licensed under GPLv2 and is based on mrouted code,
the applicable licenses are below:
