NAT
NAT (Network Address Translation) serves three purposes:
1.
Provides security by hiding internal IP addresses. Acts like firewall.
2.
Enables a company to access internal IP addresses. Internal IP addresses that are only available
within the company will not conflict with public IP.
3.
Allows a company to combine multiple ISDN connections into a single internet connection.
