Bandwidth Management
Bandwidth management allows you to allocate network resources according to defined
policies. This policy-based bandwidth allocation helps your network to better handle real-time
applications such as Voice-over-IP (VoIP).
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 ZyWALL VPN is based on the IPSec standard and is
fully interoperable with other IPSec-based VPN products.
X-Auth (Extended Authentication)
X-Auth provides added security for VPN by requiring each VPN client to use a username and
password.
Certificates
The ZyWALL can use certificates (also called digital IDs) to authenticate users. Certificates
are based on public-private key pairs. Certificates provide a way to exchange public keys for
use in authentication.
SSH
The ZyWALL uses the SSH (Secure Shell) secure communication protocol to provide secure
encrypted communication between two hosts over an unsecured network.
HTTPS
HyperText Transfer Protocol over Secure Socket Layer, or HTTP over SSL is a web protocol
that encrypts and decrypts web sessions. Use HTTPS for secure web configurator access to the
ZyWALL

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 ZyWALL firewall supports TCP/UDP
inspection, DoS detection and prevention, real time alerts, reports and logs.
