Title: Default internet traffic and transparent passthrough

Abstract: A method for routing packets sent from a user to the internet is provided for systems in which the user is connected to a private network. The method includes: extracting a source network address from the packet; using said source network address to retrieve a user profile for the user; examining said user profile to determine whether to route the packet through the private network or to route the packet directly to the Internet; and routing said packet according to said profile. This allows a user or network provider to choose whether to route packets destined for the Internet directly to the Internet rather than through the private network, thus preventing excessive network traffic on the private network.
