Troubleshooting

Check the 10M/100M 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.

Can’t ping any workstation on the
LAN.

Verify that the IP address and the subnet mask are consistent
between the ZyWALL and the workstations.

The WAN IP is provided when the ISP recognizes the user as an
authorized user after verifying the MAC address or 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. We recommend you configure this
menu anyway 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/xDSL 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.

Can’t connect to a remote node or
ISP.

Check menu 24.1 to verify the line status. If it indicates Down, then
refer to the section on the line problems.
