Testing Your Configuration
The process of communication to the Internet works as follows when your
MultiCom Firewall and workstation computers are configured properly.
1. Your computer makes a request to reach the Internet or a service from the
Internet.
2. This request is sent to the network through your ethernet card/interface.
3. Your ethernet card/interface forwards this information to the MultiCom
Firewall
4. Your MultiCom Firewall takes this information and forwards it to your
modem or directly to the ISP if the modem is in “bridge” mode
5. your modem, unless already connected will dial your Internet Service
Provider, authenticate your user name and password and then send
information request to the Internet
The information that you requested will follow the same route back (in the
opposite order) to reach the computer making the request. In most cases you will
either get the information that you received, get a response that it was not found,
or because of network congestion be told that your request has timed-out and was
dropped.
To test that your connections are working correctly you can open your preferred
Internet browser (Netscape Navigator or Microsoft's Internet Explorer) and type
in a web address.
NOTE — please hit the refresh page on your browser to be sure that
you are getting information from the Internet directly instead of from a
web page saved to your hard disk. You should also notice the lights on
your MultiCom Firewall blinking.
