Abstract
Facilitating packet flow in a communication network includes receiving at a defender a request packet sent from a node. The request packet is communicated to a load balancer operable to communicate the request packet to a network element server selected from a plurality of network element servers. The request packet has a destination address associated with the load balancer. A response packet is received from the network element server. The response packet has a tunnel endpoint address. Whether the tunnel endpoint address corresponds to an approved network element server is determined. The response packet is communicated to the node if the tunnel endpoint address corresponds to an approved network element server.
