Hi,
I want to ask you if it is possible to enable wake on lan. I have one mk with nat and couple machines behind it. I wont to wake some machine from internet. I think it is not possible directly but if router could send some packet action-based (for example: incoming connection to port 1122 -> sending magic packet to mac xx:xx:Xx:xx:xx)

You may find some help here:

Is it possible to add WOL functionality from within MikroTik RouterOS?
What would be of great importance, is to be able from within our router, which is running RouterOS e.g. v3.x,
to wake-up a remote WOL-supporting computer.

E.g. etherwake is a tool in Linux that performs exactly the above function.
Could such functionality be embedded in RouterOS?

I would like if MT create simple tool for wake up in simple click is it possible ?
