[Cerowrt-devel] dnsmasq ipv6 stuff

[Richard Brown]

[Sorry - I realized an earlier request asked to see the auto-generated /var/etc/dnsmasq.conf file. It's appended ]

> I'm still confused about using CeroWrt 3.7.3-2 to give out v6 addresses to my laptop (it's not working). Here's what I see:
> 
> - I'm using the HE.net 6in4 tunnel to get a /48 for my home. The router itself has a good v6 address, and can ping global v6 addresses. 
> 
> - ifconfig in the router shows that each of the five interfaces (se00, sw00, sw10, gw00, gw10) have addresses assigned from my /48 (see the network file below).
> 
> - The only uncommented lines in the /etc/dnsmasq.conf file are a "enable-ra" and a set of dhc-range lines for each of the interfaces. (see below) The prefixes for each of the interfaces match the prefixes in the ifconfig command.
> 
> - I have not modified /etc/config/dhcp, as it didn't seem to make any difference what I put there.
> 
> Any thoughts? Thanks.
