OpenVpn using Debian


If you are using a VM and Debian to create an openvpn connection to the internet. Can you use port forwarding? Do you need to use the gateway of Virtualbox for connecting the ip address of wan address with the gateway of virtual box? Is the broadcasting address of virtual box the same as the gateway?
I do not have the background nor do I understand how networking does what it does, so I am trying to learn since I think things like openvpn, and security, as it is today, are important even for the the home user


Yes, you can setup firewall rules to forward traffic in and out for hosted VM. It all depended upon your setup. Is public IP assigned directly to the router or your desktop?
