Features and Applications

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

2.1 Features

The ZyWALL's security features include VPN, firewall, anti-virus, content filtering,
IDP (Intrusion Detection and Prevention), ADP (Anomaly Detection and
Protection), and certificates. It also provides bandwidth management, NAT, port
forwarding, policy routing, DHCP server and many other powerful features.
The rest of this section provides more information about the features of the
ZyWALL.
High Availability
To ensure the ZyWALL provides reliable, secure Internet access, set up one or
more of the following:
• Multiple WAN ports and configure load balancing between these ports.
• One or more 3G (cellular) connections.
• An auxiliary (backup) Internet connection.
• A backup ZyWALL in the event the master ZyWALL fails (device HA).
Virtual Private Networks (VPN)
Use IPSec, SSL, or L2TP VPN to provide secure communication between two sites
over the Internet or any insecure network that uses TCP/IP for communication.
The ZyWALL also offers hub-and-spoke IPSec VPN.
Flexible Security Zones
Many security settings are made by zone, not by interface, port, or network. As a
result, it is much simpler to set up and to change security settings in the ZyWALL.
You can create or remove zones. You can add interfaces and VPN tunnels to
zones.
