funny question

it’s possible to reach other side let say i got MikroTik on B location, but i want to change my public ip or clone my ip because i don’t like other side see my real ip. Can MikroTik do that?

Not alone - it has to become a client of some VPN server. Bear in mind that you need to get the responses and that your public IP is assigned to you by your ISP. So you can src-nat the packets you send to any address you want, but even if your ISP would let such packets through (which is not likely), the remote party would send its responses to that other address so they would never reach you.

sindi i was waiting for your answer.

I was thinking to do VPN between two MikroTik and from my side if i want to access someone “mark routing” (mark where i want to go) and fly where want to fly

Thanks
