Question

DPort forwarding

Explanation

NAT (Network Address Translation) allows multiple devices on a private internal network to share a single public IP address assigned by the ISP. The router translates private IP addresses (e.g., 192.168.x.x) to the one public static IP when traffic goes out to the Internet, and reverses the translation for incoming responses. Without NAT, only one device could use the single public IP at a time. WPS is a simplified Wi-Fi setup feature unrelated to Internet sharing. MAC filtering restricts which devices can connect to the router but does not enable Internet sharing. Port forwarding directs inbound traffic to a specific internal host but is not required for basic outbound Internet access.
