Abstract
A method and system are described for resolving problems created by implementing multiple networks using private IP addresses and layer two tunneling protocols is described. A network processing system is operable to map flows from private IP addresses and ports on layer two tunneling protocol networks to public IP addresses and ports using the private IP addresses and ports and identifiers for the layer two tunneling protocol network. The network processing system uses its own public IP addresses and ports to anchor the traffic from the private network and performs the required mapping to pass traffic between the public and private networks.
