ABSTRACT:
Apparatus, systems, and methods may operate to establish a virtual private network (VPN) connection between a server in a private network and a client in a public network. Additional activities include intercepting a socket call from the client requesting resolution of a network address associated with a domain name in the private network, searching a local linked list for the network address, returning the network address to the client if the network address is found in the local linked list, and, if the network address is not found in the local linked list, sending a request to resolve the network address to a domain name system (DNS) server in the private network. Additional apparatus, systems, and methods are disclosed.
