Jeff, a network administrator, needs to forward HTTP traffic from a firewall public IP to the internal web server's private. IP Which of the following can Jeff implement?
A. DNS
B. NAT
C. PKI

IP address. The main reason you need to do this (as pointed out earlier in the section “IP Addressing”) is because there simply aren’t enough IPv4 addresses to go around. Using NAT means that only one registered IP address is needed on the system’s external interface, acting as the gateway between the internal and external networks.

authentication system.
