[Cerowrt-devel] cerowrt 3.7.2-3 released, still in a battle with ipv6

[Robert Bradley]

Just using "enable-ra" did not seem to work for me, so I needed to add 
the dhcp-range entries too.  Once that's done though, you get AAAA and A 
records in DNS, so ping6 works fine.  Unlike IPv4 though, you also get 
all the addresses for systems connected to both wired and wireless 
thanks to the constant DUID.  Lease duration is set via the "48h" part 
assuming it works as it should.
