Port forwarding issue or.....

Hi. straight to my problem, I should say i can wake my system on lan via mikrotik terminal, so there is no problem with this.
The problem is here that i cant do it via remote system, I set up DDNS, no problem with using winbox via remote computer.
I accept incoming /forwarding port (12002 for this specific job) I made NAT rule for dst-nat but this was not my solution.
can anyone help?
