Abstract
A method and system for distributed network address translation for mobile network devices. A mobile network device requests one or more locally-unique ports with a Port Allocation Protocol from a second network device on a first network to identify the first network device on the first network if the mobile first network device roams to a second external network. One or more default or ephemeral ports on the mobile network device are replaced with one or more locally-unique ports obtained with the Port Allocation Protocol. The one or more locally-unique ports allow distributed network address translation to be used with the mobile network device. A combination network address is created for the mobile network device with a locally unique port and an external network address for the first network to identify the mobile first network device if the mobile first network device roams to a second external network.
