Abstract
Disclosed are methods and apparatus for handling data having an embedded address (and port). In general terms, a host of a private network is operable to obtain from its corresponding edge router a global address (GA) and optionally an additional global port range (GPR). When the host then wishes to transmit data out of the private network, the obtained GA (and GPR) may then be used for an embedded address (and port) within data sent by the host to a public network. The obtained GA (and GPR) may also be used by the host to translate its own source address and port in its IP and/or TCP/UDP header if needed.
