Part I:

Getting Started

This part helps you get to know your Prestige, introduces the web configurator and covers how to configure the Wizard Setup screens.


Introducing the Web Configurator 1-1

Chapter 1 Getting to Know Your Prestige

This chapter introduces the main features and applications of the Prestige.

1.1 Prestige Internet Security Gateway Overview The Prestige is the ideal secure gateway for all data passing between the Internet and LANs. By integrating NAT, firewall and VPN capability, ZyXELs Prestige is a complete security solution that protects your Intranet and efficiently manages data traffic on your network. The embedded web configurator is easy to operate.

1.2 Prestige Features The following sections describe Prestige features.

1.2.1 Physical Features 10/100M Auto-negotiating Ethernet/Fast Ethernet Interface(s) This auto-negotiation feature allows the Prestige to detect the speed of incoming transmissions and adjust appropriately without manual intervention. It allows data transfer of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending on your Ethernet network. Auto-crossover 10/100 Mbps Ethernet Interface(s) These interfaces automatically adjust to either a crossover or straight-through Ethernet cable. 4-Port Switch A combination of switch and router makes your Prestige a cost-effective and viable network solution. You can add up to four computers to the Prestige without the cost of a hub. Add more than four computers to your LAN by using a hub. Time and Date The Prestige allows you to get the current time and date from an external server when you turn on your Prestige. You can also set the time manually. Reset Button The Prestige reset button is built into the rear panel. Use this button to restore the factory default password to 1234; IP address to 192.168.1.1, subnet mask to 255.255.255.0 and DHCP server enabled with a pool of 32 IP addresses starting at 192.168.1.33.


1-2 Introducing the Web Configurator

1.2.2 Non-Physical Features IPSec VPN Capability Establish a Virtual Private Network (VPN) to connect with business partners and branch offices using data encryption and the Internet to provide secure communications without the expense of leased site-to-site lines. The Prestige VPN is based on the IPSec standard and is fully interoperable with other IPSec-based VPN products. Firewall The Prestige is a stateful inspection firewall with DoS (Denial of Service) protection. By default, when the firewall is activated, all incoming traffic from the WAN to the LAN is blocked unless it is initiated from the LAN. The Prestige firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts, reports and logs. Content Filtering The Prestige can also block access to web sites containing keywords that you specify. You can define time periods and days during which content filtering is enabled and include or exclude a range of users on the LAN from content filtering. Brute-Force Password Guessing Protection The Prestige has a special protection mechanism to discourage brute-force password guessing attacks on the Prestiges management interfaces. You can specify a wait-time that must expire before entering a fourth password after three incorrect passwords have been entered. Please see the appendices for details about this feature. Packet Filtering The packet filtering mechanism blocks unwanted traffic from entering/leaving your network. Universal Plug and Play (UPnP) Using the standard TCP/IP protocol, the Prestige and other UPnP enabled devices can dynamically join a network, obtain an IP address and convey its capabilities to other devices on the network. Call Scheduling Configure call time periods to restrict and allow access for users on remote nodes. PPPoE PPPoE facilitates the interaction of a host with an Internet modem to achieve access to high-speed data networks via a familiar "dial-up networking" user interface. PPTP Encapsulation Point-to-Point Tunneling Protocol (PPTP) is a network protocol that enables secure transfer of data from a remote client to a private server, creating a Virtual Private Network (VPN) using a TCP/IP-based network.


Introducing the Web Configurator 1-3

PPTP supports on-demand, multi-protocol and virtual private networking over public networks, such as the Internet. The Prestige supports one PPTP server connection at any given time. Dynamic DNS Support With Dynamic DNS (Domain Name System) support, you can have a static hostname alias for a dynamic IP address, allowing the host to be more easily accessible from various locations on the Internet. You must register for this service with a Dynamic DNS service provider. IP Multicast Deliver IP packets to a specific group of hosts using IP multicast. IGMP (Internet Group Management Protocol) is the protocol used to support multicast groups. The latest version is version 2 (see RFC 2236); the Prestige supports both versions 1 and 2. IP Alias IP Alias allows you to partition a physical network into logical networks over the same Ethernet interface. The Prestige supports three logical LAN interfaces via its single physical Ethernet LAN interface with the Prestige itself as the gateway for each LAN network. SNMP SNMP (Simple Network Management Protocol) is a protocol used for exchanging management information between network devices. SNMP is a member of the TCP/IP protocol suite. Your Prestige supports SNMP agent functionality, which allows a manager station to manage and monitor the Prestige through the network. The Prestige supports SNMP version one (SNMPv1). Network Address Translation (NAT) Network Address Translation (NAT) allows the translation of an Internet protocol address used within one network (for example a private IP address used in a local network) to a different IP address known within another network (for example a public IP address used on the Internet). Traffic Redirect Traffic Redirect forwards WAN traffic to a backup gateway on the LAN when the Prestige cannot connect to the Internet, thus acting as an auxiliary backup when your regular WAN connection fails. Port Forwarding Use this feature to forward incoming service requests to a server on your local network. You may enter a single port number or a range of port numbers to be forwarded, and the local IP address of the desired server. DHCP (Dynamic Host Configuration Protocol) DHCP (Dynamic Host Configuration Protocol) allows the individual client computers to obtain the TCP/IP configuration at start-up from a centralized DHCP server. The Prestige has built-in DHCP server capability, enabled by default, which means it can assign IP addresses, an IP default gateway and DNS servers to all

systems that support the DHCP client. The Prestige can also act as a surrogate DHCP server (DHCP Relay) where it relays IP address assignment from the actual real DHCP server to the clients. Full Network Management The embedded web configurator is an all-platform web-based utility that allows you to easily access the Prestiges management settings and configure the firewall. Most functions of the Prestige are also software configurable via the SMT (System Management Terminal) interface. The SMT is a menu-driven interface that you can access over a telnet connection. RoadRunner Support In addition to standard cable modem services, the Prestige supports Time
