What to do to connection with external communication
For dealing with external communication, the Web server must have a static IP. Having a static IP could also be a problematic issue. As far as Web servers generate dynamic IP addresses (those addresses assigned to users when they connect to the server and this changes every time they log into the Intranet), the entire network is safe as the hacker or attacker would never be able to detect from where the request or information has actually originated. The NAT equipment serves as address translator from internal to external IP address and vice versa and routing them within these private addresses.
