Sonic.net VPN

As you suspect, it is the later. If you're directly on Sonic's network, there shouldn't be an issue. But, if you like being extra careful, you could use it at home as well.

Not sure if I'm correct about this, but I think the purpose of VPNs is to encrypt the data across an unsecured network. If you are connected to sonic directly, the path it'll take would just end up at a different node of sonic's network before it gets sent out "unencrypted" to the internet. It does hide your real IP though, but I believe connections that are sent to your VPN address are still able reach you. Also, firewalls don't really work well with VPNs since the data is encapsulated. If you had a home wifi connection though, I guess using it would prevent others from listening to the traffic you send over wifi. If you run a web server or use bittorrent behind a NAT router, using your computer as a VPN client should expose all your ports to the internet, so you wouldn't need to setup port forwarding. Maybe someone else with more knowledgeable would shed some light on this. =D

Zento has this all about right.

The primary point of the VPN service is to allow you to access a "trusted" network at Sonic.net, while travelling, on Wi-Fi, etc.
