For example, I have two PC, the IP address (already set as static) of one is
192.168.1.1 and another one is
In each of them, I need to use two ports, e.g. 300 and 400
So I would need to use links as below:
192.168.1.1:300 192.168.1.1:400 192.168.1.2:300 192.168.1.2:400
So does that mean I need to do port forwarding 4 times? Or I only need to do port forwarding for an IP, for example
192.168.1.1 and then there would be some way I could access all the ports for that IP?
