Guessing because I haven’t used v6 over ppp, but: - You probably need net.inet6.ip6.accept_rtadv set to 1 to accept IPv6 router advertisement from upstream. You should get a prefix from the upstream router. - You may also possibly need to run rtsold(8). > Regards, > > oh > > -- Bob Bishop r...@gid.co.uk
