28.1 Problems with a LAN Interface
Table 28-2 Troubleshooting the LAN Interface
PROBLEM CORRECTIVE ACTION
Check your Ethernet cable type and connections. Refer to the Rear Panel and
Connections section for LAN connection instructions.
Cannot access
the ZyWALL
from the LAN.
Make sure your Ethernet card is installed and functioning properly.
Check the 10M/100M LAN LEDs on the front panel. One of these LEDs should be on. If
they are both off, check the cables between your ZyWALL and hub or the station.
Cannot ping
any computer
on the LAN.
Verify that the IP address and the subnet mask of the ZyWALL and the computers are
on the same subnet.
28.2 Problems with the WAN Interface
Table 28-3 Troubleshooting the WAN interface
PROBLEM CORRECTIVE ACTION
The WAN IP is provided when the ISP recognizes the user as an authorized user after
verifying the MAC address, Host Name or User ID.
Find out the verification method used by your ISP.
If the ISP checks the LAN MAC Address, tell the ISP the WAN MAC address of the
ZyWALL. The WAN MAC can be obtained from menu 24.1.
In case the ISP does not allow you to use a new MAC, you can clone the MAC from the
LAN as the WAN MAC and send it to the ISP using Menu 2 - WAN Setup. It is
recommended that you configure this menu even if your ISP presently does not require
MAC address authentication.
If the ISP checks the Host Name, enter host name in the System Name field in Menu 1 -
General Setup when you connect the ZyWALL to a cable/ads modem.
Cannot get
WAN IP from
the ISP.
If the ISP checks the User ID, make sure that you have entered the correct Service Type,
user name (in the My Login field) and password (in the My Password field) in Menu 4 -
Internet Access Setup.
