From 070a46121dff0cf233e4c12f2a5bae6c9300c0eb Mon Sep 17 00:00:00 2001 From: Arjen de Korte Date: Fri, 12 May 2017 11:26:49 +0200 Subject: [PATCH] dnsmasq: add IPv6 nameserver configuration in server mode When in ra server mode, configure nameservers passed in router announcements from the dns value (which is already used by odhcpd). This also fixes FS#677 by using the global IPv6 address of the router instead of the link local address (if no nameservers are configured).
