Another option. On both sides - on the ADSL modem of the working and home wifi router, if the address is white dynamic - raise dyndns or analogues (if the address is gray, then talk to the provider - maybe they will forward the port for you). On the modem (router), forward the RDP port to the computer (it is better to choose a port for forwarding not RDP from 10000 to 65535) and practice)
