PCP policies

Overview

PCP operates between subscribers and NAT directly. This protocol provides the subscriber with limited but direct control over the NAT function. PCP configuration is supported on the 7750 SR.

PCP allows a customer to configure static port forwards, obtain information about existing port forwards and to obtain the outside IP address from software that runs on the home network or the CPE.

A PCP policy allows you to configure PCP parameters that affect the function of a NAT PCP server. The policy is applied to multiple NAT PCP servers so that they behave consistently.
