Hi, nullv you can try to add "-A OUTPUT -m addrtype --dst-type
MULTICAST -j DROP" / "-A OUTPUT -m pkttype --pkt-type multicast -j
DROP" to ip6tables or try to remove multicast with ip maddr

> I've been using radvd to set up a group of clients using RA broadcasts. I also have a group of client PCs using static IPv6 in a different ::/64 subnet altogether but on the same physical network. The two networks have to remain separate for security reasons.
> The problem I'm having is that clients on the two separate networks can still "see" each other through the automatic link-local (fe80::) addresses. I've added the line IPv6_AUTOCONF=no to network & my ifcfg-* files but I can't seem to stop this behaviour.
