Nexland ISB SOHO: Introduction

A Note About the Firewall
The ISB SOHO protects your computers from intrusion by its firewall feature. It
prevents an outsider from gaining access to the computers connected to the ISB. It will
not protect your computers against information requested from
inside
though. This is
the case when you download a suspect program or e-mail with an attachment that has
harmful virus code.
The ISB SOHO should be used in conjunction with Anti-Virus software (with an e-
mail scan feature) to provide the best protection. With this software, your computer is
better protected against Viruses and e-mail born Trojan programs.
Remember, to be safe, you should never open e-mails with attachments
that end in “.exe” or “.vbs” …even if they’re from someone you know.
As e-mail Trojans take over a computer and send their destructive
payload to contact lists automatically.
If you work in an office environment, installing a good Personal Firewall on each
computer provides an even better measure of protection. This protects a computer’s
data internally on the LAN from another computer on the same LAN. Some personal
firewalls have additional features to make sure only registered applications use the
network; this prevents Trojan FTP programs and the like from working. The ISB Pro
series of routers from Nexland comes with personal firewall software for this very
reason.

Safety First
Make sure you follow these precautions and your ISB SOHO will last you a very
very very long time:
Follow all warnings, notes, and instructions marked on the ISB.
To protect the unit from overheating make sure it is not blocked or covered.
Do not use or store the ISB in an environment that exceeds temperature and
humidity specifications.
Do not place the ISB near a radiator or heat register, or in a built-in installation
unless adequate ventilation is provided.
Before cleaning the ISB, unplug from wall outlet. Do not use liquid cleaners or
aerosol cleaners. Use a damp cloth for cleaning.
Do not place cords or cables where they may be walked on or tripped over.
Be sure to comply with any applicable local safety standards or regulations.
General-purpose cables are provided with the ISB. Any cables or other
requirements mandated by local authority are your responsibility.
Cables that are attached to devices in different locations that have different power
sources and grounding may have hazardous voltage potentials. Consult a qualified
electrical consultant before installing the ISB to see if this phenomenon exists and,
if necessary, take corrective action.
Never touch annunciated telephone wires or terminals unless the line has been
disconnected.
Avoid using telephone equipment or installing the ISB during an electrical storm.
Never install telephone jacks, lines, network cables, the ISB, or power
connections in wet locations.
Never spill liquid of any kind on the ISB.
