You are the network administrator for a small company that implements NAT to access the Internet. You recently acquired five servers that must be accessible from outside your network. Your ISP has provided you with five additional registered IP addresses to support these new servers, but you don't want the public to access these servers directly. You want to place these servers behind your firewall on the inside network, yet still allow them to be accessible to the public from the outside. Which method of NAT translations should you implement for these five servers?
A. Dynamic
B. Overloading
C. Restricted
D. Static
