What is Double NAT and How It Happens?

The double NAT can sometimes be a sign of trouble. On a home network, you usually connect to the internet through a single router with a public IP address. You then give each device its own private IP address.

But you may often be behind more than one router, like in schools, hostels, hospitals, and other places with advanced networking. In the case of a Double NAT, our devices have two private IP addresses, which is different from a single router. This can cause problems when playing online games, opening certain ports, or even connecting a VPN.

Double NAT makes it so that devices connected to the first private network can’t talk to devices connected to the second private network. So, Double NAT may be the reason you can’t join the team chat room or host the Modern Warfare server.
