CHAPTER 4
4.3.7.2 Network Address Translation - NAT
Network Address Translation can be used to give multiple
users access to the Internet with a single user account, or to
map the local address for an IP server (such as Web or FTP)
to a public address. This secures your network from direct
attack by hackers, and provides more flexible management
by allowing you to change internal IP addresses without
affecting outside access to your network. Note that NAT
must be enabled to provide multi-user access to the Internet
or to use the Virtual Server function.
