Figure 47: Internet Screen
DMZ
This feature, if enabled, allows the DMZ computer on your LAN to be exposed to all
users on the Internet.
· This allows almost any application to be used on the "DMZ PC".
· The "DMZ PC" will receive all "Unknown" connections and data.
· If the DMZ feature is enabled, you must select the PC to be used as the "DMZ PC".
The "DMZ PC" is effectively outside the Firewall, mak-
ing it more vulnerable to attacks. For this reason, you
should only enable the DMZ feature when required.
Special Applications
If you use Internet applications which use non-standard connections or port numbers,
you may find that they do not function correctly because they are blocked by the ADE-
4300/ADW-4300. In this case, you can define the application as a "Special Application".
The Special Applications screen can be reached by clicking the Special Applications
button on the Internet screen.
You can then define your Special Applications. You will need detailed information
about the application; this is normally available from the supplier of the application.
Also, note that the terms "Incoming" and "Outgoing" on this screen refer to traffic from
the client (PC) viewpoint
