Port Management

1. Overview

This screen provides tools for managing port forwarding (port mapping) configurations on CPE devices. Operators can create, view, update, and delete port mapping rules to facilitate access to internal network services from external networks. Each port mapping defines how traffic is directed from an external port to a specific internal client and port.

2. Functionality and Usage

2.1. Viewing Port Mappings

  • Select CPE ID Type – Choose Serial or MAC to identify the device.

  • Enter CPE ID – Provide the serial number or MAC address of the device.

  • Get Port Mappings – Click to retrieve current port mapping configurations from either:

    • Device (via ACS) – Retrieves real-time data directly from the device.

    • Database – Retrieves last known configuration from the ACS database.

Retrieved port mapping information includes:

  • Object name (full TR path of the port mapping)

  • Description (port mapping name/label)

  • Protocol (TCP, UDP, or TCP/UDP)

  • Internal client (IP address of the target device)

  • Internal port

  • External port

  • Remote host (if specified)

2.2. Creating Port Mappings

  • Description – Provide a name or label for the port mapping.

  • Internal Client – Enter the IPv4 address of the internal device that will receive the forwarded traffic.

  • Internal Port – Specify the destination port number (0-65535) on the internal client.

  • External Port – Specify the port number (0-65535) that will be accessible from the external network.

  • Protocol – Select the transport protocol:

    • TCP – Transmission Control Protocol

    • UDP – User Datagram Protocol

    • TCP/UDP – Both protocols (if supported by the device)

  • Remote Host – Optionally restrict the mapping to traffic from a specific external IPv4 address.

  • Reprovision – Choose whether to store the mapping for re-application after device reboots.

2.3. Updating Port Mappings

  • Object Name – Select the port mapping instance to modify (full TR object path).

  • Modify Parameters – Change any of the available parameters:

    • Description

    • Internal client

    • Internal port

    • External port

    • Protocol

    • Remote host

  • Reprovision – Choose whether to store the updated mapping for re-application after device reboots.

2.4. Deleting Port Mappings

  • Select Mappings – Choose one or more port mapping entries from the list of existing mappings.

  • Delete Selected – Remove the selected port mappings from the device.

  • Confirm – Verify the deletion operation before it’s executed.

3. Status Codes

  • 100 – Success

  • 201 – No device found

  • 202 – Database error

  • 203 – Incorrect request structure or non-writable parameter

  • 204 – General error

  • 205 – ACS connection error
