Set up VPN server that can give valid IP address to clients

Hello

I’m away from my country and because of coronavirus I don’t know when I can get back.

The problem is I need to access some banking and government sites in my country that only can be accessed only with the same country’s IP addresses.

I have a Mikrotik router connected to the internet at home (that I’m away from it) and I have remote access to it and can configure it.

Can you please guide me on how can I set up a VPN server on that router, that I can connect to it with my laptop or my iPhone and get that country’s IP address through it?

I appreciate your help
Thank you
