In a corporate setting where the Internet is brought in via a high-speed line, there are typi-
cally machines between the outside Internet and the internal network. These machines
include a combination of proxy servers and firewalls that filter and multiplex Internet traf-
fic. In the configuration below, the Intellicom board could be given a fixed address so any
of the computers on the local network would be able to contact it. It may be possible to
configure the firewall or proxy server to allow hosts on the Internet to directly contact the
controller, but it would probably be easier to place the controller directly on the external
network outside of the firewall. This avoids some of the configuration complications by
sacrificing some security.
If your system administrator can give you an Ethernet cable along with its IP address, the
netmask and the gateway address, then you may be able to run the sample programs with-
out having to setup a direct connection between your computer and the Intellicom board.
You will also need the IP address of the nameserver, the name or IP address of your mail
server, and your domain name for some of the sample programs.
