Chapter 1 Getting to Know Your ZyWALL 57
The 10/100 Mbps auto-negotiating Ethernet ports allow the ZyWALL to detect the speed of
incoming transmissions and adjust appropriately without manual intervention. They allow data
transfers of either 10 Mbps or 100 Mbps in either half-duplex or full-duplex mode depending
on your Ethernet network. The ports are also auto-crossover (MDI/MDI-X) meaning they
automatically adjust to either a crossover or straight-through Ethernet cable.
Dial Backup WAN
The dial backup port can be used in reserve as a traditional dial-up connection when/if ever the
WAN, (or WAN 1, 2) and traffic redirect connections fail.
Time and Date
The ZyWALL allows you to get the current time and date from an external server when you
turn on your ZyWALL. You can also set the time manually. The Real Time Chip (RTC) keeps
track of the time and date.
Reset Button
Use the reset button to restore the factory default password to 1234; IP address to 192.168.1.1,
subnet mask to 255.255.255.0 and DHCP server enabled with a pool of 32 IP addresses
starting at 192.168.1.33.
Dual PCMCIA and CardBus Slot
The dual PCMCIA and CardBus slot provides the option of a wireless LAN. You can
alternatively insert a ZyWALL Turbo Card to use the anti-virus and IDP features.
IEEE 802.11 b/g Wireless LAN
The optional wireless LAN card provides mobility and a fast network environment for small
and home offices. Users can connect to the local area network without any wiring efforts and
enjoy reliable high-speed connectivity.
1.2.2 Non-Physical Features
Load Balancing
The ZyWALL improves quality of service and maximizes bandwidth utilization by dividing
traffic loads between the two WAN interfaces (or ports).
Transparent Firewall
Transparent firewall is also known as a bridge firewall. The ZyWALL can act as a bridge and
still have the capability of filtering and inspecting the packets between a router and the LAN,
or two routers. You do not need to do any other changes to your existing network.
