The NAT Configuration Screens

8.1 Overview

Use these screens to configure port forwarding and trigger ports for the OX253P.
You can also enable and disable SIP, FTP, and H.323 ALG.

Network Address Translation (NAT) maps a host

’

s IP address within one network

to a different IP address in another network. For example, you can use a NAT
router to map one IP address from your ISP to multiple private IP addresses for
the devices in your home network.

8.1.1 What You Can Do in This Chapter

•

The

General

screen (

Section 8.2 on page 77

) lets you enable or disable NAT

and to allocate memory for NAT and firewall rules.

•

The

Port Forwarding

screen (

Section 8.3 on page 78

) lets you look at the

current port-forwarding rules in the OX253P, and to enable, disable, activate,

and deactivate each one.

•

The

Trigger Port

screen (

Section 8.4 on page 82

) lets you maintain trigger port

forwarding rules for the OX253P.

•

The

ALG

screen (

Section 8.5 on page 85

) lets you enable and disable SIP

(VoIP), FTP (file transfer), and H.323 (audio-visual) ALG in the OX253P.
