rule (PCP)


Hierarchy Level


Configure a rule to assign the port control protocol (PCP) server that handles selected traffic. PCP enables hosts to operate servers for a long time (as in the case of a webcam) or a short time (for example, while playing a game or on a phone call) when behind a NAT device, including when behind a carrier-grade NAT operated by their ISP. PCP enables applications to create mappings from an external IP address and port to an internal IP address and port.

PCP is supported on the MS-DPC, MS-100, MS-400, and MS-500 MultiServices PICS. Starting in Junos OS Release 17.4R1, PCP is also supported on the MS-MPC and MS-MIC.
