How to change NAT type to open

Easy steps to change NAT type to open :

Let's understand what is NAT?

NAT - Network Address Translation - It is a networking concept used by network router to share one public IP address among multiple private addresses.

Let's consider you have 4 computers in the network. Each computer requies IP address in order to communicate with other computer and get Internet access.
You have Internet service provider and your service provider has given you one Internet modem. Now this Internet modem will assign only one public IP address. You can connect only one computer to the modem and get public IP address to get on the Internet.
Now if you connect modem to the router, then modem will assign IP address to the router. You can connect all the 4 computers to the router. Router will assign it's own private IP address to all the computers in order to communicate with them. In this way only one public IP address is used and 4 private IP addresses to get all the 4 computers on the Internet.
This is the basic function of all the routers.

In case of gaming devices they need to communicate with the public IP address. If you have connected router behind router then you will get strict NAT issue.
Some DSL Internet service provider's modem acts as a router. You connect your router to that router. In this case there are 2 routers in the network.

There are 3 types of NAT issues with the gaming devices.

Open NAT: This means the settings on the router are good and you are able to play the online games.
Moderate NAT: In this case you can talk to other players online who have open or moderate NAT.
Strict NAT: In this case you can not talk to the players who have moderate or strict NAT.

How to change NAT type to open?

If you are using DSL Internet service then make sure that your modem is in bridge or PPPoE mode.
