No, you're just thickheaded, and just fundamentally don't understand network routing.
If you stand in a line of people and someone ELSE hands you something into your left hand, and you then pass it along to the person on your right that's ROUTING.
If you reach over and pickup something with your left hand YOURSELF and pass it along to the person on your right THAT'S NOT ROUTING.
Same deal with copying files. If your computer copies the file that's not routing. It'd only be routing if the other computers (on either side) made a connection request at the TCP/IP stack level, independent of anything you're running on the computer, and it went through. VPN clients do not do this. They do not act as network routers, they act as a client for that workstation to make it's own connection into the distant remote network.
Wrong. Unless the laptop is deliberately configured to pass packets AND the remote end is also configured then nothing will get passed. On a desktop machine you'd have to enable Internet Connection Sharing over a the PPTP/L2TP VPN link. Then the remote end would also have to have been configured to pass packets. It's not enough for just one side of a routing connection to get things going.
Well, you've certainly demonstrated you truly have no grasp of network routing principles. If that encourages others to read up on the matter then that's great.
