Features
The UGate-3200P incorporates many advanced features, carefully designed
to provide sophisticated functions while being easy to use.
LAN Features
• 7-Port Switch.
The UGate-3200P incorporates a 7-port Switch. Both
10BaseT and 100BaseT connections can be used simultaneously.
•
DHCP Server Support.
Dynamic Host Configuration Protocol pro-
vides a dynamic IP address to PCs and other devices upon request. The
UGate-3200P can act as a DHCP Server for devices on your local LAN.
•
Multi Segment LAN Support.
LANs containing one or more seg-
ments are supported, via the UGate-3200P's built-in static routing table.
If NAT (Network Address Translation) is disabled, the UGate-3200P will
function as a static router.
Internet Access Features
• Shared Internet Access.
All users on the LAN can access the Inter-
net through the UGate-3200P, using only one single external IP
Address. The local (invalid) IP Addresses are hidden from external
sources. This process is called NAT (Network Address Translation).
•
DSL & Cable Modem Support.
The UGate-3200P has a 10BaseT
Ethernet port for connecting DSL or Cable Modem. All popular DSL and
Cable Modems are supported.
•
PPPoE Support.
Connect to your ISP using PPPoE (PPP over
Ethernet), if your ISP uses this method.
•
Fixed or Dynamic IP Address.
On the WAN connection, the UGate-
3200P supports both Dynamic IP Address (IP Address is allocated on
connection) and Fixed IP Address.
Configuration & Management
• Easy Setup.
Use your WEB browser from anywhere on the LAN for
configuration.
•
Remote Management.
The UGate-3200P can be managed from a
workstation anywhere on the WAN, using a WEB browser.
Advanced Internet Functions
• Virtual Servers.
This feature allows Internet users to access Internet
servers on your LAN. The required setup is quick and easy.
•
User-Defined Virtual Servers.
Internet users can access non-
standard Internet Servers on your LAN by using this feature.

Introduction
3
• Special Internet Applications.
Internet applications such as Inter-
net Videoconferencing, Telephony, Games Servers, and other special-
purpose Servers are supported.
•
DMZ.
One (1) PC on your local LAN can be configured to allow unre-
stricted 2-way communication with Servers or individual users on the
Internet.
Security Features
• Configuration Data
. Optional password protection is provided to
prevent unauthorized users from modifying the configuration.
•
Access Control Features
. The LAN Administrator can limit Internet
access by individual PCs.
•
Firewall Protection.
All incoming data packets are monitored and all
incoming server requests are filtered, thus protecting your network from
malicious attacks from external sources. (This protection is lost if NAT is
disabled.)
Firewall Protection
The firewall protection provided by the UGate-3200P is an intrinsic side
effect of NAT (Network Address Translation). All users on the LAN share
a single external IP address. From the external viewpoint, there is no net-
work, only a single device.
For internal users, the UGate-3200P acts as a “transparent proxy server”,
translating the multiple internal IP addresses into a single external IP ad-
dress.
For external requests, any attempts to connect to local resources are
blocked. The UGate-3200P will not “ reverse translate” from a global IP
address to a local IP address.
This type of “natural” firewall provides an impregnable barrier against ma-
licious attacks.
