Should I enable NAT-PMP?
Always turn this off. Better yet, don’t buy a router that supports it. UPnP and NAT-PMP are two different protocols that do the same thing – they let devices on your network poke holes in the router firewall. This makes setup of some new devices easier, but is a huge security hole.
Should I enable UPnP NAT?
Should I use UPnP? If security is a concern, it is highly recommended that UPnP be disabled on the gateway (router). If UPnP is enabled on the gateway, internal devices may open services from the internet without your knowledge.
What is NAT-PMP used for?
The NAT Port Mapping Protocol (NAT-PMP) is a network protocol that is used for the automatic establishment of network address translation settings and port forwarding configurations, with no effort from the user.
What is NAT-PMP and is it for gaming?
These are a set of networking protocols that allow networked devices to discover each other on the network and share data. As an example Printers, Cameras and gaming consoles all use UPnP / NAT-PMP to find each other on a network.
What does UPnP do on a router?
UPnP (Universal Plug and Play) is a networking protocol that enables devices to discover each other and connect without the need for manual configuration or user intervention. The protocol automates all the steps necessary for recognition and communication between devices on the same network.

How do I enable NAT-PMP?
Go to the airport utility, click on the airport icon and then click on edit. Go to the network tab. Then click on network options.. you should find it is on by default. Enable NAT Port Mapping Protocol.
When should I enable NAT?
NAT is now essential when it comes to conserving global address space. The IPv4 protocol, which determines how all devices on the internet communicate, has a limited number of available IP addresses. If every device that connects to the internet required a unique IP address, we would soon run out.
Is Nat PMP secure?
Security Concerns UPnP and NAT-PMP are a classic example of the “Security vs. Convenience” trade-off. By their very nature, these services are insecure. Any program on the network can allow in and forward any traffic – a potential security nightmare.
