You have just installed a new web server on the Certkiller network. You are required to ensure that the web server is accessible from the Internet. The network uses private addressing, so and IP-to-registered address mapping is required. To do this, you entered the following command: CK(config)# ip nat inside source static 192.168.2.1 198.18.1.254 You unsuccessfully try to ping the Internet from the PC host on the LAN. During the troubleshooting process, you enter the "show ip nat translations" command but the output is blank. What is the most likely cause of the problem?
