The process is indeed a few simple steps:<div><br></div><div>1) remove dnsmasq & dnsmasq-dhcpv6, then install again (see Dave Täht's note below)</div><div>2) Add config to /etc/dnsmasq.conf to hand out DHCPv6 addresses (as suggested by Robert Bradley)</div><div>3) Tweak the firewall to put henet 6in4 tunnel into WAN zone</div><div>3) Bring up henet and restart network, firewall, dnsmasq</div><div><br></div><div>There's a fully-functional script at: <a href="http://www.bufferbloat.net/attachments/download/165/tunnelbroker.sh">http://www.bufferbloat.net/attachments/download/165/tunnelbroker.sh</a> that does this.
