1.2 Features of The ZyWALL 50
The following are the main features of the ZyWALL 50.
Auto-negotiating 10/100Mbps Ethernet LAN
This auto-negotiation feature allows the ZyWALL 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.
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 50 VPN is based on the IPSec standard and is fully interoperable with other IPSec-based VPN
products. The ZyWALL 50 supports up to 50 runtime SAs (Security Associations).
Firewall
The ZyWALL 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 ZyWALL firewall supports TCP/UDP inspection, DoS detection and prevention, real time alerts,
reports and logs.
