NAT (Network Address Translation)

NAT Features

Translation: Translates between public and private IP addresses
IP address assignment: Includes a simple DHCP server and can assign IP addresses to clients; uses private IP addresses
DNS name resolution: Acts as a DNS server; forwards DNS requests to an Internet DNS server and returns the results to clients.

NAT Versus ICS

  • ICS uses a single checkbox rather than complex configuration information.

  • ICS uses a fixed range of private IP addresses.

  • ICS only allows one public IP address.

  • ICS can only be used on one internal LAN interface.
