Wat zijn UPnP servers?

Universal Plug and Play (UPnP) is een verzameling computerprotocollen. De bedoeling van deze verzameling is dat apparaten draadloos met elkaar kunnen worden verbonden in woon- en kantooromgevingen. Het baseert zich op standaarden uit de internetcommunicatie.

Hoe werkt UPnP?

Universal Plug and Play (UPnP) is een protocol waarmee apparaten in je netwerk waarvoor UPnP aanstaat, elkaar automatisch kunnen vinden, met elkaar kunnen communiceren en ook directere communicatiekanalen met internet kunnen maken.

What does NAT PMP stand for?

The NAT Port Mapping Protocol ( NAT-PMP) is a network protocol for establishing network address translation (NAT) settings and port forwarding configurations automatically without user effort. The protocol automatically determines the external IPv4 address of a NAT gateway, and provides means for an application…

What is NAT-PMP and how does it work?

To address the port mapping issue, NAT-PMP emerged, which allows client s to operate more like a host directly connected to the public network. NAT-PMP allows client hosts to communicate with the NAT gateway to request the creation of inbound mappings on demand.

What is the UPnP and NAT-PMP service?

The UPnP and NAT-PMP service on pfSense®, found at Services > UPnP & NAT-PMP, enables client PCs and other devices such as game consoles to automatically allow required inbound traffic. There are many popular programs and systems which support UPnP, such as Skype, uTorrent, mIRC, IM clients, Wii U, PlayStation 4, and XBox One.

Are UPnP and NAT-PMP insecure?

NAT-PMP is also handled by miniupnpd and uses UDP port 5351. As of this writing, the UPnP and NAT-PMP service on current versions of pfSense supports IPv6, but client support is still spotty. UPnP and NAT-PMP are a classic example of the “Security vs. Convenience” trade-off. By their very nature, these services are insecure.
