I cannot believe that I've failed to mention Hamachi until know. They have one of the cleanest security and communications products I've seen. Security systems often are as difficult for the users as they are for attackers. addresses, you traffic is unseen by the normal scanners. While you can still be seen by packet capturing systems, it's nice to be invisible to most attackers. On top of this, Hamachi creates a private network between you and the people on your network. Because Hamachi uses its own IPHamachi includes a fairly high level of security. I've used the system and found it to be easy to use. Give it a try.
