Correct Answer: The correct NAT rule to forward web-browsing traffic from the internet to the server at 10.1.1.22 is option C. In option C, the source IP is set to any, and the destination IP is the external IP address 206.15.22.9. The source zone is the Internet, indicating the traffic is coming from the internet. The destination zone is also the Internet, which is correct for a NAT rule as it addresses the interface before the translation. The destination service is set to 80/TCP, which is standard for web traffic. The action is Destination NAT, meaning it translates the external IP to an internal IP. The translated IP is correctly set to 10.1.1.22, and no translated port is specified, which is appropriate as you typically translate the same port number in many configurations.
