The Moderate, Type 2 NAT, as well as Strict, Type 3 NAT, limits the connections that can be created between your gaming console or PC and someone else’s gaming consoles or PCs. NAT2 is a single layer of public-to-private conversion, and requires assisted port forwarding to achieve inbound connections to the PS4. If you control the port forwarding on your home router, you should be able to get the PS4 to run in NAT1 mode, even on an internal RFC1918 address. If your internet connection has a public IP address (non-RFC1918, non-RFC6598) on the exterior interface of your home router, you should be able to have your PS4 run in NAT2 mode. Ultimately, an Open/Type 1 NAT will provide the best connection quality whereas Moderate and Strict NAT restrict the connections between a gaming console or PC. NAT1 is a direct connection to the internet all ports are accessible, with no port forwarding rules required. Moving on, the 3 NAT types, when concerning gaming consoles/PCs, PS3/PS4, or the Xbox 360/Xbox One, are NAT offers the dual functions of security and address conservation and is typically implemented in remote-access environments.īasically, NAT allows a single device, such as a router, to act as an agent between the Internet (or public network) and a local network (or private network), which means that only a single unique IP address is required to represent an entire group of computers to anything outside their network. This provides additional security by effectively hiding the entire internal network behind that address. NAT operates on a router, usually connecting two networks together, and translates the private (not globally unique) addresses in the internal network into legal addresses, before packets are forwarded to another network.Īs part of this capability, NAT can be configured to advertise only one address for the entire network to the outside world. It enables private IP networks that use unregistered IP addresses to connect to the Internet. Network Address Translation (NAT) is designed for IP address conservation.
