Table 100 Troubleshooting the WAN Interface
PROBLEM CORRECTIVE ACTION
Cannot get WAN IP
address from the
ISP.
The ISP provides the WAN IP address after authentication. Authentication may
be through the user name and password, the MAC address or the host name.
Use the following corrective actions to make sure the ISP can authenticate your
connection.
You need a username and password if you're using PPPoE or PPTP
encapsulation. Make sure that you have entered the correct Service Type , User
Name and Password (the user name and password are case sensitive). Refer
to Chapter 4 on page 65 .
If your ISP requires MAC address authentication, you should clone the MAC
address from your computer on the LAN as the ZyWALL's WAN MAC address.
Refer to Chapter 4 on page 65 . It is recommended that you clone your
computer's MAC address, even if your ISP presently does not require MAC
address authentication.
If your ISP requires host name authentication, configure your computer's name
as the ZyWALL's system name. Refer to Section 2.5 on page 53 .
Table 101 Troubleshooting Internet Access
PROBLEM CORRECTIVE ACTION
Cannot access the
Internet.
Connect your cable/DSL modem with the ZyWALL using the appropriate cable.
Check with the manufacturer of your cable/DSL device about your cable
requirement because some devices may require crossover cable and others a
regular straight-through cable.
Refer to Chapter 4 on page 65 and verify your settings.
Table 102 Troubleshooting the Password
PROBLEM CORRECTIVE ACTION

restore all of the factory defaults including the password. See Section 2.3 on
page 45 for details.
