Two RB760iGS (hEX S) in series. One does PPPoE and both do IKEv2.
Running:
RouterOS 6.46Beta / Winbox 3.19 / MikroTik APP 1.3.1
Having an Android device, use https://github.com/M66B/NetGuard/releases (no root required)

In the setup of IP->DNS set the max TTL to a lower value like 01:00:00
This will clean these entries after 1 hour so they do not accumulate so much.
