The following table describes the labels in this screen.

Table 54 NAT General

LABEL DESCRIPTION

Network Address

Translation

Network Address Translation (NAT) allows the translation of an Internet protocol

address used within one network (for example a private IP address used in a local

network) to a different IP address known within another network (for example a

public IP address used on the Internet).

Select the check box to enable NAT.

Default Server In addition to the servers for specified services, NAT supports a default server. A

default server receives packets from ports that are not specified in the Application

screen.

If you do not assign a Default Server IP address, the ZyXEL Device discards all

packets received for ports that are not specified in the Application screen or

remote management.

Apply Click Apply to save your changes back to the ZyXEL Device.

Reset Click Reset to begin configuring this screen afresh.

10.4 NAT Application Screen

Port forwarding allows you to define the local servers to which the incoming services will be

forwarded. To change your ZyXEL Device’s port forwarding settings, click Network > NAT

> Application. The screen appears as shown.

Note: If you do not assign a Default Server IP address in the NAT > General screen,

the ZyXEL Device discards all packets received for ports that are not specified

in this screen or remote management.

Refer to Appendix I on page 275 for port numbers commonly used for particular services.
