ABSTRACT:
A method of virtual routing an overlapping IP address using a virtual private network (VPN) device connected to a virtual private network (VLAN). The method comprises the step of receiving an overlapping Internet protocol (IP) address from a virtual site, the overlapping IP address having a virtual site address tag (Vsite) associated with a client. The overlapping IP address is converted into a non-overlapping IP address. The non-overlapping IP address is then converted into an overlapping IP address having a virtual local area network (Vlan) tag, wherein the virtual local are network tag (Vlan) is associated with at least one local area network (LAN) within the virtual private network.
