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. SVN-Revision: 34008
