Study Notes

Accessing Internal Server on the Internet

The administrator has a server with an RFC1918 private IP address and wants to make its hosted services accessible on the internet using one of the company's public IP addresses.

Solution

The administrator should configure a technology that allows mapping the internal RFC1918 address to the public IP address to allow access.

Recommended Configuration

Port Address Translation (PAT) or One-to-One NAT (Network Address Translation) should be configured to allow access to the internal server's services from the internet using the company's public IP address.
