CHAPTER 10 Network Address Translation (NAT) 10.1 Overview This chapter discusses how to configure NAT on the ZyXEL Device. NAT (Network Address Translation - NAT, RFC 1631) is the translation of the IP address of a host in a packet, for example, the source address of an outgoing packet, used within one network to a different IP address known within another network. 10.1.1 What You Can Do in the NAT Screens • Use the NAT screen (Section 10.2 on page 82) to configure the NAT settings. • Use the DMZ screen (Section 10.3 on page 83) to configure the DMZ settings. • Use the Virtual Server screen (Section 10.4 on page 84) to forward incoming service requests to the server(s) on your local network. • Use the IP Address Mapping screen (Section 10.5 on page 86) to change your ZyXEL Device's address mapping settings. 10.1.2 What You Need To Know About NAT Inside/Outside Inside/outside denotes where a host is located relative to the ZyXEL Device, for example, the computers of your subscribers are the inside hosts, while the web servers on the Internet are the outside hosts. Public/Local Public/local denotes the IP address of a host in a packet as the packet traverses a router, for example, the local address refers to the IP address of a host when the packet is in the local network, while the public address refers to the IP address of the host when the same packet is traveling in the WAN side.
