Hello,

I am following this tutorial to set up a VPN in Debian:

https://www.hugeserver.com/kb/how-to-config-openvpn-ubuntu-debian/

when I have the keys and the "server.conf" already configured, I issue "ifconfig", and find out that I have not the necessary "tun0" interface.

¿Why is that so?

Besides, I expected to need 2 physical interfaces: one for the incoming traffic and the second to give VPN access to internal resources. I don't understand why "tun0" solves this issue and how....

Many thanks in advance!
