Getting to Know Your ZyWALL
This chapter introduces the main features and applications of the ZyWALL.
1.1 The ZyWALL 10 Internet Security Gateway
The ZyWALL 10 is a dual Ethernet Internet Security Gateway integrated with a robust firewall and network
management features designed for home offices and small businesses to access the Internet via Cable/ADSL
modem or Internet router. By integrating NAT and firewall capability, ZyXEL’s ZyWALL 10 provides not
only ease of installation and Internet access, but also a complete security solution to protect your Intranet and
efficiently manage data traffic on your network. The ZyWALL Web Configurator is a breeze to operate and
totally independent of the operating system platform you use.
1.2 Features of The ZyWALL 10
The following are the essential features of the ZyWALL 10.
Firewall
Firewall with Stateful Inspection and DoS (Denial of Service) protection. By default, when the firewall is
activated all incoming traffic from the WAN to the LAN is blocked. The ZyWALL firewall supports
TCP/UDP inspection, DoS (Denial of Services) detection and prevention, real time alerts, reports and logs.
Note: You can configure most features of the ZyWALL 10 via SMT but we recommend
you configure the firewall and Content Filters using the ZyWALL Web Configurator.
Content Filtering
The ZyWALL can block web features such as ActiveX controls, Java applets, cookies as well as disable web
proxies. The ZyWALL can also block specific URLs by using the keyword feature.
Packet Filtering
The Packet Filtering mechanism blocks unwanted traffic from entering/leaving your network.
PPPoE
PPPoE facilitates the interaction of a host with a 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.
PPTP supports on-demand, multi-protocol, and virtual private networking over public networks, such as the
Internet. The ZyWALL supports one PPTP server connection at any given time.
