Abstract:
1. A method comprising: establishing, at a virtual private network gateway, a virtual address for a client having a first physical interface and a first physical address for communicating via a non-secure access network; establishing, for the client, a virtual interface corresponding to the virtual address that enables the client to access a secure network via the non-secure access network and via the virtual private network gateway; responsive to detecting that the client has a second physical interface and a second physical address configured to communicate via a second access network in addition to the non-secure access network, determining whether the second physical address is a secure address within the secure network; and responsive to determining that the second physical address is a secure address within the secure network, recognizing the virtual address as a valid address within at least a portion of the secure network, wherein at least some of network traffic for the virtual address is routed to the second physical interface instead of to the virtual private network gateway.
