15. What is the purpose of port forwarding?
16. A network administrator is configuring a static NAT on the border router for a web server located
in the DMZ network. The web server is configured to listen on TCP port 8080. The web server is paired
with the internal IP address of 192.168.5.25 and the external IP address of 209.165.200.230. For easy
access by hosts on the Internet, external users do not need to specify the port when visiting the web
server. Which command will configure the static NAT?

R1(config)# ip nat inside source static tcp 209.165.200.230 80 192.168.5.25 8080

R1(config)# ip nat inside source static tcp 192.168.5.25 8080 209.165.200.230 80 *

R1(config)# ip nat inside source static tcp 209.165.200.230 8080 192.168.5.25 80

R1(config)# ip nat inside source static tcp 192.168.5.25 80 209.165.200.230 8080

17. What is a characteristic of unique local addresses? 18. Which statement describes IPv6 ULAs?
19. Refer to the exhibit. Based on the output that is shown, what type of NAT has been implemented?

PAT using an external interface *

static NAT with one entry

dynamic NAT with a pool of two public IP addresses

static NAT with a NAT pool
20. Match the steps with the actions that are involved when an internal host with IP address
192.168.10.10 attempts to send a packet to an external server at the IP address 209.165.200.254
across a router R1 that is running dynamic NAT. (Not all options are used.)
