Abstract
A roaming client in communication with an enterprise site through a virtual private network (VPN) gateway maintains an address for a virtual network interface upon becoming a resident client at the enterprise site. A physical interface for the resident includes two valid addresses. Seamless data networking is achieved while promoting routing efficiency by reducing the amount of local traffic addressed to and from the virtual address that is unnecessarily routed through VPN gateways.
