Technical Summary
Perhaps the most common use of IPsec is in providing virtual private
networking capabilities. One very popular use of VPNs is to provide
telecommuter access to the corporate Intranet. Today NATs are widely
deployed in home gateways, as well as in other locations likely to be
used by telecommuters, such as hotels. The result is that IPsec-NAT
incompatibilities have become a major barrier to deployment of IPsec
in one of its principal uses. This draft describes known
incompatibilities between NAT and IPsec, and describes the
requirements for addressing them.
