Thank you for purchasing the ISA-4000 Internet Server. The ISA-4000 was designed specifically for
SOHO type enterprises and home users.
The ISA-4000 has many versatile functions for use in supporting SOHO Internet and Intranet
services. You can configure your office setup using a single ISA-4000 that provides an interface
between several workstations operating different operating systems and the Internet. Alternatively,
you can configure several ISA-4000 devices to act as Web, email, and file servers for the company
Intranet. Refer to
1.7 Configuration Options
for more information.
The ISA-4000 enables users to share a single ADSL or cable modem among all workstations in your
SOHO environment, and has basic firewall features integrated to enhance Intranet security. The

flexibility in sharing files.
The ISA-4000 is the best choice for your SOHO Internet server requirements.
