Chapter 8 Troubleshooting

Connections

How many computers can be connected through the Modem?
The Modem is capable of

253

connections, but having no more than

45

connec-

tions is recommended. As the number of connections increases, the available
speed for each computer decreases.

Security

What is the default username for the Modem?
The default username for the router is admin (all lower case). To activate the
password to protect the Modem, change the default password, which is blank (no
password) by default. Remote management is not available on the Modem until
the default password is changed.

Does the Modem function as a firewall?
Yes. The Modem provides its security through the use of a

NAT and SPI

(Stateful

Packet Inspection)

firewall, which acts as a physical barrier between your net-

work and the Internet.

What is NAT and how does it protect my network?

NAT

(Network Address Translation) is a type of security that masks the private

IP

addresses of the computers on your network with a single public

IP

address. With

NAT

, the private

IP

address of the computers on your network is never transmit-

ted over the Internet.

Which Virtual Private Networking (VPN) protocols are supported?
The Modem supports pass-through for

PPTP

,

L2TP

, and

IPS

ec.

Can I use Internet firewall or security programs with my network?
Because the Modem has firewall security, it is not necessary to use any other pro-
gram for security. The use of third-party firewall or Internet security software is
not recommended, since certain programs create problems on a private network
(BlackIce Defender, Norton Internet Security, or ZoneAlarm, for example).
