Unifi upnp configuration – universal plug n play

UPnP (Universal Plug’n’Play) is a protocol that allows programs on a host to configure port forwardings on their NAT-Router automatically. UpnP effectively allows a program to instruct the router to open required ports without the user’s interference or inspection. As a result, allowing UPnP on your router poses a security risk: a worm or malware program might theoretically use this feature to compromise the security of the entire LAN.
As a result, it’s best to set up port forwarding manually wherever possible and disable UPnP. In certain cases, however, dynamic port forwarding is necessary, rendering manual port forwarding impractical, leaving the user with little choice but to allow UPnP.
You must also add changeset 25251: it’s a simple matter of editing /etc/init.d/miniupnpd, which you can do directly on your live router using nano; please be aware that if the patch is not applied correctly, miniupnpd can stop working.

The NAT Port Mapping Protocol (NAT-PMP) is a network protocol for automatically configuring network address translation (NAT) and port forwarding configurations without the need for user interaction.

1st The protocol automatically specifies a NAT gateway’s external IPv4 address and provides a way for an application to communicate communication parameters to peers. Apple introduced NAT-PMP in 2005 as a replacement for the more widely used ISO Standard[2] Internet Gateway Device Protocol, which is used in many NAT routers. The Internet Engineering Task Force (IETF) released the protocol as an informational Request for Comments (RFC) in RFC 6886.
The User Datagram Protocol (UDP) is used by NAT-PMP, and port 5351 is used. Since forwarding a port usually does not enable any operation that could not be accomplished using STUN methods, it has no built-in authentication mechanisms. NAT-PMP has the advantage over STUN in that it does not need a STUN server and a NAT-PMP mapping has a known expiration period, enabling the application to avoid sending expensive keep-alive packets.

I’m a little perplexed because it appears that there are two separate protocols for configuring a NAT, UPnP/IGD and NAT-PMP. I’m not sure which one to use. Is it true that all NATs help them both? Should I support both in order to ensure that the NAT can support at least one of them?
Since NAT-PMP (now PCP) is an IETF draft, it should be the one you use. However, you should allow your application to silently fallback to UPnP/IGD for compatibility reasons, as not all NAT devices support PCP/NAT-PMP, and many older devices only support UPnP/IGD.
Stick to hole punching with UDP. Except for 4G LTE networks (which also have random port allocation) and routers that block ALL UDP traffic, it works on almost all routers. You can use secure UDP if you need to send data efficiently.

Windows 10 : how to start or stop upnp device host service

Previously, I had learned that UPnP could open ports on its own (perform Port Forwarding on a router) in response to a request from a host on the local network. However, the nuances of how this happens, as well as the protocols employed, have remained a mystery to me until now.
In this post, I’ll go over how two port forwarding protocols, the NAT Port Mapping Protocol and the Internet Gateway Device (IGD) Protocol, both of which are part of the UPnP protocol set, work. Surprisingly, I discovered that knowledge on this subject is scarce in RuNet, leading me to write this note.
A: To set up a rule on a router to forward a particular TCP/UDP port (Port Forwarding), not manually, but “automatically,” i.e. in response to a request from a host on the internal network. Q: How is this going to be implemented?
A: The system behind NAT sends a request to the router with the internal and external port numbers, as well as the protocol type (TCP/UDP). If the requested external port is available, the router creates a broadcast rule for itself and informs the requesting device that the request was successful. Q: Does the router verify or approve requests to open ports?
