Could someone please help me solve this, i have this huge spam on my mikrotik, and it keeps mobile phones awake, it constantly sends this packets to basically all devices on network, but i cant figure whats causing it or how to block it (blocking this ports doesnt help)
This is screenshots of torch to my HTC10, this thing spams around 400 of this basicaly all the time, my phone is awake(wlan wake) 8 straight hours every time am at work, when i come home its just fine
This is IPv6 LLMNR - Link Local Multicast Name Resolution (basically mDNS for IPv6).
If not used, it could easily be blocked with either a bridge filter or firewall rule. Or probably even be disabled in your phone.

It spams all devices, so i need to block it on Router, but please tell me HOW!?
I tried adding general drop rule to my phone IP without any exclusions, and packets still go thru and keep device awake, im unable to block this!
As I have (yet) no active IPv6 on routerOS this code might need some modification:
/interface bridge filter
add name=drop-llmnr chain=forward action=drop mac-protocol=ipv6 in-bridge=<yourlocalbridge> dst-address=ff02::1:3
In case you don’t use or need multicast at all, you can simplify it with:
/interface bridge filter
add name=drop-multicast chain=forward action=drop packet-type=multicast in-bridge=<yourlocalbridge>
And make sure you ticked “Use IP Firewall” in Bridge Settings.

Oh, i was looking at wrong place(ip firewall)->bridge filter!Thanks man!
I was unable to add first rule, as dst-adress is greyed out, also doesn’t alow me to add via command line.
But anyways, i disabled all multicast AFIK dont need it.
All this weird packets to my phone and other devices stooped, and whats funny my web pages even load faster now!(very noticeable), ddint even expect that!
Thank you very much again for help!
