[Cerowrt-devel] CeroWrt 3.10.18-1 odd firewall warnings

[Jim Gettys]

Dave helped me get up a HE IPv6 tunnel.

There were two things:
1) when I change routers, Comcast gives me a different IPv4 address, so I
had to update the Hurricane information to correspond.
2) CeroWrt is using a new version of dnsmasq, which has good support for
IPv6, and IIRC, Dave turned on the dnsmasq support and turned off 6relayd,
or some such...

Been working fine for me since.
