(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.
Virtual Private Networks (VPN)
Use IPSec, SSL 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 your own custom zones. You can add interfaces and VPN tunnels to
zones.
