appropriate cable.
Check with the manufacturer of your Cable/xDSL modem about the

crossover cable and for others regular patch cable.
Cannot access the
Internet.
Verify your settings in Menu 3.2 and Menu 4.
21.5 Problems with the Firewall
Problem Corrective Action
You can ONLY configure the firewall via Prestige Web Configurator
or CI command. You will not be able to access the Prestige Web
Configurator from the WAN if:
The firewall is activated, as the firewall by default, blocks all WAN to
LAN traffic. To access the Prestige 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.
Cannot configure the
firewall.
You have an SMT console session running.
