There is a lot of information at the following link. If they do, neither of them will be able to connect to the internet. Every computer has at least one ip address, and two computers should never have the same ip address. IP addresses are four sets of numbers separated by periods that allow computers to identify each other. So the port forwarding configuration will not work. When this happens the ports will no longer be forwarded to your computer's ip address. This will probably work when you initially set it up, but after restarting your computer it may get a different ip address.
When you have port forwarding setup, your router forwards ports to an ip address that you specify. It is very important to setup a static ip address, if you are going to use port forwarding. J(Last Updated: September 17, 2021) | Reading Time: 5 minutes
