Abstract
In some networking situations, securing an inner packet of a tunnel packet requires an intermediary networking device knowing a destination address of the secured inner packet. Consequently, an identity of a secured network is known to others and presents a security risk. The provided technique addresses this risk by: i) establishing at a first security interface a first secured network connection between a first and second secured network, the connection established for a first packet addressed to a virtual security interface and destined for the second secured network; and ii) responding to a network condition by establishing at a second security interface at least one second secured network connection between the first and second secured network, the connection established for a second packet addressed to the virtual security interface and destined for the second secured network.
