[Cerowrt-devel] dnsmasq setup (was Re: 3.10.15-5 released)

[Dave Taht]

Well, it looks like the problem lies somewhere in how openwrt
generates dnsmasq's conf file, which has changed since august
somewhere. It's not the new dnsmasq that is at fault.

It incidentally has been YEARS since I looked at how this stuff got
setup, and it can be improved. Notably I was trying to use a web proxy
by default early on and I have no idea if the dhcp method works for
that on anything nowadays. (?)

(Although I supply a wpad address here I do not supply the relevant
wpad proxy data by default. I guess I should get around to documenting
that or removing the functionality)

(does anyone besides me use polipo?)

Anyway, this is what cerowrt 3.7.5 did for /var/etc/dnsmasq.conf
(mildly modified for my internal setup here). I'm about to wipe this
particular router and install 3.10.15-5. (I've also been reviewing the
existing firewall rules in light of some changes since feburary, and
they can be improved also....)
