A client computer hosts a virtual private network tool to establish a virtual private network connection with a remote network. Upon startup, the virtual private network tool collects critical network information for the client computer, and sends this critical network information to an address assignment server in the remote network. The address assignment server compares the critical network information with a pool of available addresses in the remote network, and assigns addresses for use by the client computer that do not conflict with the addresses for local resources. The address assignment server also provides routing information for resources in the remote network to the virtual private network tool. The virtual private network tool will postpone loading this routing information into the routing tables of the client computer until the client computer requests access to a specific resource in the remote network. When the client computer requests access to a specific resource in the remote network, the virtual private network tool will only provide the routing table with the routing information for that specific remote resource.

Secure access to remote resources over a network

Techniques for determining which resource access requests are handled locally at a remote computer, and which resource access requests are routed or 'redirected' through a virtual private network. One or more routing or 'redirection' rules are downloaded from a redirection rule server to a remote computer. When the node of the virtual private network running on the remote computer receives a resource access request, it compares the identified resource with the rules. Based upon how the identified resource matches one or more rules, the node will determine whether the resource access request is redirected through the virtual private network or handled locally (e.g., retrieved locally from another network). A single set of redirection rules can be distributed to and employed by a variety of different virtual private network communication techniques.
