	einfo the line net.ipv6.conf.all.forwarding = 1 in sysctl.conf or just run
	einfo sysctl -w net.ipv6.conf.all.forwarding=1 in your firewallscripts before
	einfo starting radvd.
	einfo
	einfo echo 1 \> /proc/sys/net/ipv6/conf/all/forwarding should also work.
	einfo
	einfo "rc-update add radvd default" should make it start at boottime.
