   A company has a web server at 10.0.0.10 and a mail server at 10.0.0.20. The company has two public IP addresses: 203.0.113.10 and 203.0.113.11. The web server must be reachable at 203.0.113.10, and the mail server must be reachable at 203.0.113.11. The administrator configured two static NAT entries.
