Hey everyone, i am wondering if it is possible to block all connections using ip6tables for local clients which have NOT privacy extensions enabled? For example most smartphones do not have PE (yet) and i would like to disable IPv6 connectivity for those completely. PC clients using a modern OS with PE enabled should be allowed to connect. I am sure ip6tables does not allow something like regular expressions to match a pattern of source & destination IP´s. Is this at all possible somehow?
