Abstract
Disclosed are methods and apparatus for handling data sent from a first public network to a second or same public network via a private network. In general terms, network translation address mechanisms are provided within the edge routers of the private network. When a first processing node sends a request to an edge router to access another processing node which resides in a public network, the edge router forms a binding based on two addresses associated with the first processing node. A first private address is initially associated with the first processing node, and the first processing node uses this private address to communicate with the private network. A second public address is also allocated to the first processing node based on the first processing node's request to communicate with a public node. The first processing node uses the allocated second public address to communicate with the requested public node.
