System Setup
System Name
System Name is a unique name to identify the NBG-418N in an Ethernet network. It is
recommended you enter your computer’s “Computer name” in this field (see
the
chapter
about wizard setup for how to find your computer’s name).
This name can be up to 30 alphanumeric characters long. Spaces are not allowed, but
dashes “-” and underscores "_" are accepted.
Domain Name
Enter the domain name (if you know it) here. If you leave this field blank, the ISP may
assign a domain name via DHCP.
The domain name entered by you is given priority over the ISP assigned domain name.
Administrator
Inactivity Timer
Type how many minutes a management session can be left idle before the session times
out. The default is 5 minutes. After it times out you have to log in with your password
again. Very long idle timeouts may have security risks. A value of "0" means a
management session never times out, no matter how long it has been left idle (not
recommended).
Password Setup
Change your NBG-418N’s password (recommended) using the fields as shown.
Old Password
Type the default password or the existing password you use to access the system in this
field.

password, the screen displays an asterisk (*) for each character you type.

time zone and Greenwich Mean Time (GMT).
Daylight Savings
Daylight saving is a period from late spring to early fall when many countries set their
clocks ahead of normal local time by one hour to give more daytime light in the
evening.
Select this option if you use Daylight Saving Time.
Start Date
Configure the day and time when Daylight Saving Time starts if you selected
Daylight
Savings
. The
o'clock
field uses the 24 hour format. Here are a couple of examples:
Daylight Saving Time starts in most parts of the United States on the first Sunday of
April. Each time zone in the United States starts using Daylight Saving Time at 2 A.M.
local time. So in the United States you would select
First
,
Sunday
,
April
and type 2 in
the
o'clock
field.
Daylight Saving Time starts in the European Union on the last Sunday of March. All of
the time zones in the European Union start using Daylight Saving Time at the same

Last
,
Sunday

o'clock
field.

Logs
16.1
Overview
This chapter contains information about configuring general log settings and viewing the NBG-
418N’s logs.
The Web Configurator allows you to look at all of the NBG-418N’s logs in one location.
16.2
What You Need to Know
An alert is a type of log that warrants more serious attention. They include system errors, attacks
(access control) and attempted access to blocked web sites or web sites with restricted web
features such as cookies, active X and so on. Some categories such as
System Errors
consist of
both logs and alerts. You may differentiate them by their color in the
View Log
screen. Alerts
display in red and logs display in black.
Alerts are e-mailed as soon as they happen. Logs may be e-mailed as soon as the log is full (see
Log Schedule
). Selecting many alert and/or log categories (especially
Access Control
) may
result in many e-mails being sent.
16.3
View Log Screen
Use the
View Log
screen to see the logged messages for the NBG-418N. Options include logs
about system maintenance, system errors, access control, allowed or blocked web sites, blocked
web features (such as ActiveX controls, Java and cookies), attacks (such as DoS) and IPSec.
Log entries in red indicate system error logs. The log wraps around and deletes the old entries after
it fills. Click a column heading to sort the entries. A triangle indicates ascending or descending sort
order.
