If you wish to get a NAT type 2 connection, then you must give a permanent IP address to your Play Station 4. When you assign an IP address, it makes sure that your console has an internal IP address even after you restart it.
Some routers enable you to assign the IP address manually. Therefore, you must check if such an option is available on your router. In case such manual assignments are not permitted, then you should set up a static IP address for your PS 4.
Search for the method to manually assign the IP address on your router. Not every router supports this feature. However, the process may vary based on the router model you are using.
If such a feature is permitted by your router, then you must give an IP address to your PS4 and you don't need to make any changes in the console. Your router will provide the internal IP address to your router which is the same as your static IP address.
Step 1: It is important for you to assign your current IP address to your PS4.
To search for this IP address, you must power on your console and then carry out the steps given below.
Step 2: Now, turn on your computer and permanently assign your PS4 the IP address, which was found in the first step.
Step 3: Once you are done assigning a particular IP address to your router. Check the connection of your PS4 and make sure it is working.
For testing the connection, carry out the steps below.
Step 4: When you forward ports on your router points, then all the traffic comes to a particular internal IP address. If you want to get a connection to NAT type 2, then below are the ports that you are going to forward to your PS4's IP address.
Step 5: Once you are done assigning the IP address to your PS4 console and you forward the right one, then you must check the connection from your console.
It can be really difficult to solve a networking problem like this. Now, your connection type will change to NAT type 2. In case you don't see this connection, then check if you have entered the correct information.
Check that the Mac address and IP address are correctly written. If you are still facing a problem, then you must check if your network is properly set up or not. Make sure there is only one router on your network or else it will be hard to configure the network.
