A company has been assigned the 203.0.113.0/27 block of IP addresses by the ISP. The company has over 6000 internal devices. What type of NAT would be most appropriate for the employee workstations of the company?
- static NAT
- port forwarding
- dynamic NAT
- PAT off the external router interface
- dynamic NAT overload using the pool of addresses
Explanation: Static NAT is used by companies that have end devices such as servers that need an external public IP address. Dynamic NAT is used by companies that own a block of public IP addresses. Port forwarding is not a type of NAT. Instead, port forwarding is a technique that is used to reach a private IP address from an external network. PAT is commonly used by home networks and small businesses. PAT or overloading can also be done by using a pool of addresses.
