 ===== UPnP/NAT-PMP =====
-UPnP (Universal Plug and Play) is a controversial protocol that allows fully dynamic (automatic) port mapping from LAN IP addresses onto the Internet. UPnP has been criticized for its poor security. With this protocol, each program that uses the network maps its own ports automatically. In the screenshot below, the WhatsApp application has mapped certain ports on FreshTomato's WAN IP/Interface.
+=== UPnP ===
-UPnP is the original implementation of this dynamic port-mapping protocol. NAT-PMP (NAT Port Mapping Protocol) is a newer, enhanced version of UPnP, designed for better compatibility with NAT routing. NAT-PMP is part of Apple's Bonjour protocol, and is often used for streaming iTunes and other media.

 If you use dynamic port forwarding, you'll probably want to enable both protocols to maintain backward compatibility.
-===== Forwarded Ports =====
-This section contains a table displaying ports that are currently forwarded (with their external and internal port numbers).
+===== Settings =====
-The **Internal Address** column displays the internal IP address of the network device that has triggered its own port mapping.
+**Enable UPnP:**  Checking this enables UPnP.
-The **Protocol** column displays which protocol (TCP or UDP) is in use for the mapping in question.
+ \\
+**Enable NAT-PMP:**  Checking this enables NAT-PMP.
  \\
-{{::port_forwarding-upnp-forwarded_ports-2023.2.jpg?819x153}}
+**Inactive Rule Cleaning:**  Sets the timeout period to remove rules counted from the last time traffic flowed.
  \\
-The **Description** column lists the name of the application program which performed the port-mapping.
+{{::port_forwarding-upnp-settings-2023.2.jpg?816}}
+ \\
-===== Settings =====
+**Cleaning Threshold:** here, set the maximum number of rules to be removed by an Interval.
-**Enable UPnP:** Enable and Disable UPnP.
-**Enable NAT-PMP:** Enable/Disable NAT-PMP.
+ \\
-**Inactive Rule Cleaning:** This sets the timeout period to remove rules counted from the last time traffic was flowing.
+**Secure Mode**: eabling this lets only the "owner LAN IP address" trigger its own mapping/unmapping.
-**Cleaning Threshold:** This sets the maximum number of rules to be removed by an Interval.
+In other words, the client is only allowed to map an incoming port to its own IP address, not to another address.
-**Secure Mode**: Allows only the "owner LAN IP" to trigger its own mapping/unmapping. In other words, the client could only map an incoming port to its own IP address, not to another IP address.

-**Enable on**: This allows you to enable UPnp/NATPMP only on certain VLANs.
+**Enable on:** this allows you to enable UPnp/NATPMP only on certain VLANs.
+ \\
+**Show in My Network Places:** if enabled, makes FreshTomato appear as a gateway in Windows' browsable LAN network (WORKGROUP or HOMEGROUP).

-**Show in My Network Places**: If enabled, this makes FreshTomato appear as a gateway in Windows' browsable LAN network (WORKGROUP or HOMEGROUP).
+**Miniupnpd custom config:** here, enter custom configuration options unavailable in the web interface.
-**Miniupnpd custom config:** In this field, you can enter custom configuration options not available in the web interface. In the image below, UPnP requests/mappings are denied for a specific IP address only.\\  \\  \\
+In the image above, all UPnP requests/mappings are denied for address 10.10.10.4, the only host on that subnet.\\ \\  \\   \\   \\   \\
