ZyXEL Communications ZYWALL 100 - Manual (Page 5)

Client IP field, your computer’s IP address must match it.
For access from the LAN, check your computer’s TCP/IP configuration. The IP address and the subnet
mask of the ZyWALL and your computer must be on the same subnet.
Cannot ping any
computer on the LAN. If the 10/100M LAN LEDs are off, check the cables between the ZyWALL and your computer or hub.
Verify that the IP address and the subnet mask of the ZyWALL and the computers are on the same subnet.
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 and does not allow you to use a new MAC, clone a MAC from the
LAN. In the SMT, use menu 2. In the web configurator, click ADVANCED, WAN and then the MAC tab.
ZyXEL recommends that you configure this menu even if your ISP presently does not require MAC address
authentication.
If the ISP checks the host name, enter your computer’s name as the system name in SMT menu 1 or in the
first screen of the web configurator’s WIZARD SETUP.
Cannot get a WAN IP
address from the ISP.
If the ISP checks the user ID, check your service type, user name, and password. In the SMT, use menu 4.
In the web configurator; click ADVANCED, WAN and the ISP tab.
Cannot access the
Internet. Make sure the cable/xDSL device is turned on and connected to the ZyWALL and the Internet.
If the ZyWALL’s WAN LED is not on, check the cable between the ZyWALL and the cable/xDSL device.
Check whether your cable/xDSL device requires a crossover or straight-through cable.
Verify your settings in SMT menus 2 and 4. In the web configurator, click ADVANCED and then WAN.
