NordVPN says no. RouterOS is getting outdated.
Implementing such services on a router is silly. You should implement it on your end device so the entire path is protected.
Furthermore, when today's protocol enforced by something like NordVPN would be implemented by MikroTik, tomorrow they
will switch to another protocol that appears to be better at that time. Look, people are already requesting Wireguard
and unimplemented IKEv2 options. It is just not possible to satisfy everyone in a commercial closed-source router.
Either get some open box that you can tinker yourself, or do it on the endpoint (PC, phone, etc).
MikroTik could include an extension possibility in the form of a "MetaROUTER light" that allows the user to run processes that
implement network functions like exotic VPNs, special DNS servers, etc.
I have suggested it before but there is total lack of response, so apparently total lack of interest.
