Netgear WGX102 사용자 설명서

Introduction

2-3

The WGX102 will log security events such as blocked incoming traffic, port scans, attacks, 
and administrator logins. You can configure the router to E-mail the log to you at specified 
intervals. You can also configure the router to send immediate alert messages to your E-mail 
address or E-mail pager whenever a significant event occurs.

•

The WGX102 prevents objectionable content from reaching your computers. The router 
allows you to control access to Internet content by screening for keywords within Web 
addresses. You can configure the router to log and report attempts to access objectionable 
Internet sites.

The WGX102 router is equipped with several features designed to maintain security, as described 
in this section.

•

Computers Hidden by NAT

 

NAT opens a temporary path to the Internet for requests originating from the local network. 
Requests originating from outside the LAN are discarded, preventing users outside the LAN 
from finding and directly accessing the computers on the LAN.

•

Port Forwarding with NAT

 

Although NAT prevents Internet locations from directly accessing the computers on the LAN, 
the router allows you to direct incoming traffic to specific computers based on the service port 
number of the incoming request, or to one designated “DMZ” host computer. You can specify 
forwarding of single ports or ranges of ports.

The WGX102 router supports the Transmission Control Protocol/Internet Protocol 

 

(TCP/IP) and Routing Information Protocol (RIP). For further information about TCP/IP, refer to

IP Address Sharing by NAT

 

The WGX102 router allows several networked computers to share an Internet account using 
only a single IP address, which may be statically or dynamically assigned by your Internet 
service provider (ISP). This technique, known as NAT, allows the use of an inexpensive 
single-user ISP account.
