From 1fe7efbddb91770c1d65912f23af607ac891a63a Mon Sep 17 00:00:00 2001 From: Steven Barth Date: Tue, 30 Oct 2012 07:14:07 +0000 Subject: [PATCH] ipv6: add 6relayd (RD-, DHCPv6- & NDP-Proxy) 6relayd is an IPv6-tool that relays IPv6-management protocols like router discovery, neighbor discovery and DHCPv6 so that clients on routed (non-bridged) interfaces can use the public address prefix, DHCPv6 and DNS-service of a master interface. This is useful to avoid NAT in chained IPv6-routers.
