NAT Type 3: The console's connection to the router is restricted due to specific security protocols not being bypassed for the sake of the PS5.įrom the definition of the PS5, the PS5 NAT type 1 means the PS5 connects to the public network directly, in other words, PS5 gets a public IP address.

NAT Type 2: Your console and router are connected, with specific security restrictions removed to enable full functionality on the PlayStation 5. NAT Type 1: There's a direct connection between your console and router without any security restrictions being enforced. The router doesn't forward the game server-initiated request, this is the symmetric NAT, also called NAT type 4. If the PS5 visited the game server 2 port 4000 (40.40.40.4:4000) before the game server 2 initiates the request, and the router forwards the request that game server 2 initiated, this is the port restricted cone, also call NAT type 3. If the router forwards the request only when the PS5 visited game server 2 before game server 2 initiates the request, this is the restricted cone, also called NAT type 2. The request from game server 2 is forwarded to PS5 unconditionally, this is the full cone NAT, also NAT type 1. The NAT is divided into four types according to the router processing: If the router creates another NAT entry, for example,, as the new 'PS5' to forward the packets to the game server 2, (In other words, the PS5 is recognized as 20.20.20.1:2000 on game server 1, and recognized as 20.20.20.1:3000 on game server 2), this is the symmetric NAT.Īfter the NAT entry (session between PS5 and game server 1) is created on the router, will the router forward the request from the game server 2 (40.40.40.4:4000)? The router uses the existed NAT entry, which is, to forward the packets, in other words, the PS5 is recognized as 20.20.20.1:2000 on both game server 1 and game server 2, in this situation, the NAT is the cone type NAT. Īfter this NAT entry creating, if the PS5 visits the game server 2 with the same source port, what will the router process this visiting request? Suppose the PS5 visits the game server 1, and the private IP address 192.168.1.100:1000 (The PS5 initiates the session using port 1000) is translated to 20.20.20.1:2000 (The router marking the NAT entry using port 2000), so, as a result, a NAT entry is created on the router. This is the working principle of NAT.įigure 2: The PS5 is NATed to the game server The router is responsible for establishing a mapping relationship to realize data forwarding. Hosts inside NAT must actively communicate with an IP on the public network if they want to communicate. NAT alleviates the problem of insufficient IPV4 addresses, and it also brings restrictions, that is, hosts outside NAT cannot actively communicate with hosts inside NAT. Since both full cone, restricted cone, and port restricted cone are the cone type NAT, in other words, we only need to know the difference between cone type NAT and symmetric NAT. The difference between them is the security policy strictness.
Both the full cone, restricted cone, and port restricted cone, are all cone types. Generally speaking, NAT can be divided into four types: full cone, restricted cone, port restricted cone, and symmetric. What is NAT type 1, NAT type2, NAT type 3, and NAT type 4? So NAT has become a standard feature of routers connected to homes and small offices because, for them, the cost of applying for an independent IP address is higher than the benefits. Network address translation is widely used in many countries. In the mid-1990s, NAT became popular as a solution to the shortage of IPv4 addresses to avoid difficulties in retaining IP addresses. But the total number IP address is limited, to match requirements that more and more device accessing the global network, technology is released to map multi private IP addresses to a single public IP address. As the main difference, the public IP address allows the devices around the globe to communicate while the private IP address is allowed to use in a small area. The IP address includes public IP addresses and private IP addresses. Then what is NAT type 2? How could I get a type 2 NAT? Whether there is NAT type 1, NAT type 3, and NAT type 4? What is NAT?īefore the NAT, we might talk about the IP address.
#GAMERANGER PORT RESTRICTED NAT ROUTER UPGRADE#
'Update is required', hit the upgrade button, but get the error that says, failed to upgrade the device, the NAT type 2 at least is required. Getting back home, plug the PS5 to start a new game.
