Internet Access; Virtual Server - Planex BLW-03FA User Manual

The BLW-03FA provides connectivity to 10/100 Mbps devices, making it easy to create
a network in small offices or homes.

Internet Access

This device supports Internet access through a DSL or cable connection. Since many
DSL providers use PPPoE to establish communications with end users, the BLW-03FA
includes a built-in client for this protocol, eliminating the need to install this service on
your computer.
Shared IP Address
The BLW-03FA shares a single IP address with up to 253 users. Using only one ISP
account, multiple users on your network can simultaneously browse the Internet.

Virtual Server

If you have a static IP address, you can set up the BLW-03FA to act as a virtual host for
network address translation. Remote users access various services at your site using the
static IP address. Then, depending on the requested service (or port number), the BLW-
03FA routes the request to the appropriate server (at an internal network IP address). This
secures your network from direct attack by hackers, and provides more flexible
management by allowing you to change internal network IP addresses without affecting
outside access to your network.
User-Definable Application Sensing Tunnel
You may define special applications that require multiple connections such as Internet
gaming, video conferencing, and Internet telephony. The BLW-03FA will then sense the
application type and open a multi-port tunnel for it.
DMZ Hosts Support
Allows a networked computer to be fully exposed to the Internet. This function is used
when the special application sensing tunnel feature is insufficient to allow an application
to function correctly.
Security
The BLW-03FA supports security features that deny Internet access to specified users, or
drop requests for specific services. The BLW-03FA's firewall also blocks common
hacker attacks, including IP Spoofing, Land Attack, Ping of Death, IP with zero length,
Smurf Attack, UDP port loopback, Snork Attack, TCP null scan, and TCP SYN flooding.
