Continuing the rPi/OpenVPN server story, this is the way it looks in action. I am connected to the Internet through my Internet on the Go hotspot. I have established an OpenVPN connection to my Raspberry Pi at home. Then, I VNC into my desktop computer, run Firefox, and, view the PCLinuxOS forum from there.

In the first picture, I am on my deChromebook with a hotspot connection to the Internet.

The terminal window in fuschia shows my OpenVPN connection. Below that, in yellow, is my wireless connection's ssid. That refreshes every few seconds, and, I normally have that visible when connected outside the house so I can see exactly what I'm connected to.

In the center, I'm juist about to VNC into my at-home desktop. My public address (which we don't care about here) is 107.xxx.2x5.xx4, and, my LAN is 192.168.11.0, with my desktop .76.

Top right, I'm hovering net_applet, and, it shows I am connected to my rPi's VPN. The 192.168.1.1 is the hotspot's LAN.

Looking at the krells, I see my wireless is up (wlan0)and I also have a tun0 connection (the VPN).

Next picture is while I am VNCing my at-home desktop while VPNing through my Raspberry Pi.
