What’s the way to stop dhcpv6 traffic out I have a rule that blocks tcp6 traffic but my sniffer is still showing that its broadcasting it. Any help would be much appreciated.

You’ll probably find it’s only talking to your router. Is there any particular reason you want to block it?

If I’m not mistaken, it will be via svchost.exe:
DHCPv6 - UDP out to ff02::1:2 port 547
LLMNR - UDP out to ff02::1:3 port 5355

Thanks a lot, just want to know what everything is

If I add to block it in global rules will that work? To block them that is? If I block something shouldn’t it not come up in wireshark?
