Troubleshooting

Table 21-4 Troubleshooting Internet Access

Connect your Cable/xDSL modem with the ZyWALL using
appropriate cable.
Check with the manufacturer of your Cable/xDSL modem about the
cable requirement because for some modems you may require
crossover cable and for others regular patch cable.
Verify your settings in Menu 3.2 and Menu 4.
You can ONLY configure the firewall via ZyWALL Web Configurator
or CI command. You will not be able to access the ZyWALL Web
Configurator from the WAN if:
The firewall is activated, as the firewall by default, blocks all WAN to
LAN traffic. To access the ZyWALL Web Configurator from the WAN
when the firewall is activated, you will need to create a firewall rule
(see the examples chapter) to allow web traffic initiated from the
WAN.
You have applied a filter in Menu 3.1 (LAN) or in Menu 11.5 (WAN) to
block Web service.
You have an SMT console session running.
