What does Port Triggering do in a router?

  1. Permanently opens incoming ports

  2. Temporarily opens incoming ports if internal IP has instigated comms

  3. Blocks all incoming ports

  4. Redirects all incoming ports to a specific IP

The correct answer is: Temporarily opens incoming ports if internal IP has instigated comms

Port Triggering is a feature that temporarily opens incoming ports on a router when an internal IP initiates communication. This allows for specific applications or devices to communicate with the outside network without leaving the ports permanently open, which can pose a security risk. The other options, permanently opening incoming ports (A), blocking all incoming ports (C), and redirecting all incoming ports to a specific IP (D), are incorrect because they do not accurately describe the functionality of Port Triggering.
