UPnP is a way to forward ports on a NAT device/router.
Universal Plug and Play in eMule's context is a way to open/forward ports on UPnP compatible routers (or modems with integrated routers). This gives a high-ID without having to open ports manually.
 UPnP Requirements
In order to use Universal Plug and Play, there are several requirements:
- The router has to support it and the option has to be activated.
- If a firewall is installed, it has to be set to allow UPnP traffic.
- The eMule Mod has to have UPnP support and the option has to be activated.
For some mods (not Morph/Stulle/Scarangel) that use the UPnP functionality from the OS:
- The operating system must support it and it's functionality must be activated.
Note: To find and fix problems with UPnP use the UPnP Test Program from the See also section.
