The Mobile IP Support for RFC 3519 NAT Traversal on the Mobile Router feature extends support for
Network Address Translation (NAT) traversal to the mobile router when the mobile router is in private
addressing space behind a NAT-enabled device and needs to register directly to the public home agent
using a private collocated care-of address (CCoA).
Network Address Translation (NAT) traversal to the mobile router when the mobile router is in private
addressing space behind a NAT-enabled device and needs to register directly to the public home agent
using a private collocated care-of address (CCoA).
NAT traversal is based on the RFC 3519 specification and defines how Mobile IP should operate to
traverse networks that deploy NAT within their network. NAT traversal allows Mobile IP to interoperate
with networks that have NAT enabled by providing an alternative method for tunneling Mobile IP data
traffic. New extensions in the Mobile IP registration request and reply messages have been added that
establish User Datagram Protocol (UDP) tunneling.
