Another VPN question

}

I have a Switch at eth0, internet eth0, wifi access point eth3

I would like to set up a VPN, or something appropriate, to connect to my media box outside my local network.

I usually boot my media box by accessing the server CLI at 192.168.1.21 and boot the server from there. Then the box has IP 192.168.1.100.

Possibel?

Edit: encrypted connection would be great! OpenVPN?
