An internal corporate server can be accessed by internal PCs, but not by external Internet users that should have access. What could be the issue?

• The default gateway router for the server does not have a default route.
• The switch port to which the server connects has an incorrect VLAN configured.
• The server does not have a private IP address assigned.
• Static NAT has not been configured properly or at all.

Explanation: NAT/PAT allows a private IP address to be translated into a public address so that external users can access internal devices. Static NAT assigns one public address to a private address and is used with internal servers.
