Receive an email a day with our articles:We are going to explain what a Double NAT is and how you can fix it on your PS4.This is a problem that can appear when you connect the console via WiFi and not directly to the main router in your home.Therefore, we are going to start by explaining what NAT and the problem called Double NAT are so that you can understand it.Then we will tell you some solutions that you can try in case you are experiencing this problem on your console.Internet in its beginnings was not thought to be such an extensive network, for that reason "only" 32 bits were reserved for addresses, the equivalent of 4,294,967,296 unique addresses, but the fact is that the number of machines connected to the Internet increased exponentially and IP addresses were running out.That is why NAT or Network Address Translation emerged.In Spanish, it is called Network Address Translation.The idea is simple, make computer networks use a range of special addresses (private IPs) and connect to the Internet using a single IP address (public IP).Come on, it is created as a kind of internal network so that all devices can connect with the same public IP.So far everything is normal, but the problems appear when we connect the console to a second router that is connected to the main one instead of directly to the Internet.Consequently, the router to which the console is connected does not receive a public IP address, which causes problems because the router is not directly visible to the servers.This problem is called Double NAT, and it is caused when this second router is used to improve your WiFi signal.In addition to homes where a second router is installed to extend the network signal, Double NAT also appears in other contexts such as hospitals, student accommodation, hotels, schools and public places.Worst of all, there is no master solution that we can get rid of when this problem appears.There is no technical solution that can be applied to solve all Double NAT problems, but we are going to tell you some that you can try to implement to mitigate its effects.Obviously, the first tip is to try to connect your PS4 to the main router in the house or your WiFi, that router that is the one that connects directly to your operator's line.If you are doing this because the coverage does not reach the room where you have the console, it is best to ask your operator for a new router with more power.And if this cannot be, then consider buying a more powerful router.Here is the shopping guide for routers that we made for you a few months ago.In the event that you can't afford a new router, you can also do a somewhat different workaround: configure your second router as if it were a switch.To do this, reset the second router and change its IP address on the local network so that it is not the same as the main router.For example, if the main is 192.168.1.1, you can put an IP 192.168.1.2 on it.Next, connect the secondary router to the first router using the LAN ports of both.By doing so, enter the configuration of the router that will act as a switch.In settings, disable DHCP server, change Gateway mode (NAT on) to Router mode (NAT off), disable wireless SSID broadcasts, disable wireless network mode, and disable firewall.If all this seems complicated to you or you are still having problems despite using a single router, try to make sure that you have the UPnP option activated, both in the router and in the console through its network settings.This parameter should take care that the connection is made automatically.And if all else fails, you can also try assigning a static IP to the console and opening the appropriate ports manually as explained in detail in VidaExtra, also configuring a DMZ.PS3 and PS4 games use TCP ports 80, 443, 5223, and 10070 - 10080, and UDP ports 3478, 3479, 3658, and 10070.However, these are much more advanced resources that may give you quite a few headaches if your knowledge is poor.In the case of Double Nat, the solution is usually to eliminate the intermediate router and connect the console to the main one whenever possible.Share Double NAT: how to solve the problem in WiFi connections on PS4More Sites You'll LikeSee more articlesSee more videos
