ABSTRACT:
Various techniques are described which may be used for improving traffic flows between private networks and public networks. According to one aspect of the present invention, a technique is described for implementing asymmetric routing in a NAT routing environment. Another aspect of the present invention provides a technique for implementing load balancing and resource allocation assignments among peers in a redundant, multiple NAT router environment.
