Make sure that you have the correct power adaptor connected to the ZyWALL and
plugged in to an appropriate power source. Check all cable connections.
If the LEDs still do not turn on, you may have a hardware problem. In this case, you
should contact your local vendor.
Check the cable connection between the ZyWALL and your computer or hub. Refer
to the Rear Panel section for details.
Ping the ZyWALL from a LAN computer. Make sure your computer Ethernet card is
installed and functioning properly.
If the 10/100M LAN LEDs are off, check the cable connections between the ZyWALL
and your LAN computers.
Verify that the IP address and subnet mask of the ZyWALL and the LAN computers
are in the same IP address range.
The WAN IP is provided after the ISP verifies the MAC address, host name or user
ID.
Find out the verification method used by your ISP and configure the corresponding
fields.
If the ISP checks the WAN MAC address, you should clone the MAC address from a
LAN computer. Click WAN and then the MAC tab, select Spoof this Computer's
MAC address - IP Address and enter the IP address of the computer on the LAN
whose MAC address you are cloning.
If the ISP checks the host name, enter your computer's name (refer to the Wizard
Setup section in the User's Guide) in the System Name field in the first screen of the
WIZARD.
If the ISP checks the user ID, click WAN and then the ISP tab. Check your service
type, user name, and password.
Check the ZyWALL's connection to the cable/DSL device.
Check whether your cable/DSL device requires a crossover or straight-through cable.
Click WAN to verify your settings.
Check that you entered the password correctly. Some ISPs may lock you out after
several unsuccessful attempts.
