Hi Eric, Thanks for the great feedback. I’m working with Daniel Golle and Noah Meyerhans on some “glue” to do the integration. First off is adding support to ISC-DHCP to allow specifying a site-wide domain, and explicit DHCP options analogous to what dnsmasq supports. That’s here: https://github.com/openwrt/packages/pull/5819 Was going to add you to the discussion but can’t figure out your Github handle. As soon as that’s merged (waiting on a sign-off from Golle) I’ll get back to working on the glue, which is in draft form. -Philip _______________________________________________ Lede-dev mailing list Lede-dev@lists.infradead.org http://lists.infradead.org/mailman/listinfo/lede-dev
