ndproxy

Implementation of IPv6 Neighbor Discovery proxy

The ndproxy(4) kernel module implements IPv6 Neighbor Discovery proxying with many options to handle several use-cases. It replies to a neighbor solicitation with a specific neighbor advertisement, in order to let the PE uplink router send further packets to a CPE downlink router, that may or may not be the same node that the one which runs ndproxy. The main difference with the ndp(8) command-line tool is that, with ndproxy(4), the host running ndp can be used only to redirect packets to another IPv6 internal router, for instance a dedicated one with hardware support of IPv6 routing processes.
