32 Chapter 1 Getting to Know Your VSG
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.
The VSG automatically performs NAT on the LAN. You can also set the VSG to perform
NAT on the WAN for VPN (IPSec and PPTP) connections.
MAC (Media Access Control) Filter
The MAC filter lets you block specific devices from accessing the Internet through the VSG.
Static Route
Static routes tell the VSG how to forward IP traffic when you configure the TCP/IP
parameters manually and disable NAT.
Subscriber Login Page Customization
You can customize the subscriber login page according to your business needs. The advanced
settings allow you to include welcome messages, a company logo and basic formatting.
Dual-function Console Port
The VSG provides a console port for local management. You can also set this console port to
act as the printer port when connected to an external statement printer.
Web Configurator Management
The VSG comes with an embedded web-based configurator. It offers advanced management
features and allows you to manage the VSG remotely using Internet Explorer (version 4.0 or
above) or Netscape (version 6.0 or later).
System Maintenance
The firmware of the VSG can be upgraded via the web configurator or the SMT menu. The
Embedded FTP server is for firmware upgrades as well as configuration file backups and
restoration.
Ease of Installation
Your VSG is designed for quick, intuitive and easy installation. It can be mounted on a
desktop or standard 19” rack.
