Port forwarding through openvpn for ps4

[gtapro151]

To make a long explanation short before setting up an openvpn, I had successfully got my nat type on my ps4 and xbox to open using this tut (https://www.youtube.com/watch?v=Q5U0nj9oaZY&t=1s). After setting up the openvpn however, the nat type has gone to strict. How do we forward ports specifically 3074 and 3075 udp and tcp though the vpn? The vpn provider does support forwarding and it is setup on that end. Forgive me if this is in the wrong area.
