Connections
How many computers can be connected through the Gateway?
The Gateway is capable of
254 connections, but having no more than 45 con-
nections is recommended. As the number of connections increases, the available
speed for each computer decreases.
Security
What is the default username for the Gateway?
The default username for the router is admin (all lower case). To activate the
password to protect the Gateway, change the default password, which is blank
(no password) by default. Remote management is not available on the Gateway
until the default password is changed.
Does the Gateway function as a firewall?
Yes. The Gateway provides its security through the use of
NAT firewall, which acts
as a physical barrier between your network 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 Gateway supports pass-through for
PPTP , L2TP , and IPS ec.
Can I use Internet firewall or security programs with my network?
Because the Gateway uses
NAT firewall security, it is not necessary to use any
other program for security. The use of third-party firewall or Internet security
software is not recommended, since certain programs create problems on a pri-
vate network (BlackIce Defender, Norton Internet Security, or ZoneAlarm, for
example).
