Can't access to other services since OpenVPN installed

[migueipod]

Hi ! First at all sorry if I write badly english... Is not my natal language.

I have installed OpenVPN server in my NAS with Ubuntu Server 16.04 and it works correctly, but the other ports of other services (SSH,Samba,FTP,Plex,Transmission...) now are unavailable. All of the services are running but i can´t acces to them, the ports doesn´t reach.

Thanks for helping.
Miguel.
