Limit IPv6 clients?
[nl] Shadow Hawkins on Tuesday, 05 February 2013 11:54:38
Is it possible to limit IPv6 to certain MAC adresses, using RADVD? Right now all my PC's connect to IPV6, including (visiting) iPads and iPhone's. I only want certain PC's to have IPv6 but Radvd broadcasts it to all.

Note btw that it is multicast that Router Advertisements use, there is actually no broadcast at all in IPv6. You have a few options: - Use VLANs (best option) - Configure radvd with a 'list of clients' (see the man page) - Stop unknown clients from receiving multicast (will break all kinds of stuff silently) - Stop unknown clients from joining the RA multicast group (better use VLANs then anyway).
