23.12 Configuring Device Mode (Zero Configuration)

Zero configuration mode provides Internet and VPN access for mobile users or telecommuters
with little or no configuration. The ZyWALL auto-detects and automatically configures many
settings. In zero configuration mode:
• The WAN interface is set to be a DHCP client.
• Auto-detection for DHCP/POE on the WAN interface is enabled.
• IP alias is disabled.
• NAT is set to SUA and full feature NAT is disabled.
• The LAN interface is set to be a DHCP server.
• Network conflict avoidance is enabled.
• The LAN MAC filter is enabled.
• The ZyWALL allows the use of only one VPN network policy. This stops unauthorized
use of the other network policies.
• NAT over IPSEC (branch tunnel VPN) is enabled.
• You can use basic INTERNET ACCESS, SECURITY and LOGS screens without
logging into the ZyWALL.
• The basic screens let you configure Internet access settings, enable or disable IDP and
anti-virus (and update the signatures) and view the logs.
• You must log in to use the advanced screens.

DESCRIPTION
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows
individual clients (computers) to obtain TCP/IP configuration at startup from a
server. Unless you are instructed by your ISP, leave the DHCP check box
selected. Clear it to stop the ZyWALL from acting as a DHCP server. When
configured as a server, the ZyWALL provides TCP/IP configuration for the
clients. If not, DHCP service is disabled and you must have another DHCP
server on your LAN, or else the computers must be manually configured. When
set as a server, fill in the rest of the DHCP setup fields.
This field specifies the first of the contiguous addresses in the IP address pool.
This field specifies the size, or count of the IP address pool.
When the ZyWALL is in bridge mode, there is no need to select or clear this
radio button.
Click Bridge to go to the Bridge screen where you can view and/or change the
bridge settings.
Use zero configuration mode to have the ZyWALL configure most settings
automatically. This is useful for travelers or telecommuters.
Click Apply to save your changes back to the ZyWALL. After you click Apply,
please wait for one minute and use the IP address you configured in the LAN
Interface IP Address field to access the ZyWALL again.
Click Reset to begin configuring this screen afresh.
