wifi port closing


I need some help on wifi port.
I have a box which is not totaly a router and 2 pc connected by wifi.
So the first one connect is 10 and the second is 11.
I want to open some ports on the on specific pc no matter what is it’s IP and close the same port on the other one.
How can I do such things ?

Thank you for your answer.


Most ports are closed by default.

Here is the way to open a port:
To open a port, for example, TCP 1723

Firewall β†’ Advanced β†’ Network Security policy β†’ Global Rules β†’ Add β†’ fill in the following:
Action: Allow
Protocol: TCP
Direction: In
Description: Incoming Port TCP 1723

Source address: Any
Destination Address: Choose MAC or Host Name
Source Port: Any
Destination Port: 1723

Then push Apply β†’ Ok.

Thank you Eric, I’ll do that.
