Appendix A. DMZ 'Exposed Computer'
This feature, if enabled, allows one (1) computer on your LAN to be exposed
to all users on the Internet, allowing unrestricted 2-way communication between
the "DMZ, Exposed Computer" and other Internet users or Servers.
- Internet users will see the PC as having the IP Address shown on
the External LAN Port screen of this device. (This is the same IP Address
used by the Virtual Servers.)
- Any Internet user who knows this address can connect to the Exposed Computer.
(What happens after connection depends on what software both computers are
using).
- This allows connection to special-purpose servers which require proprietary
client software, or 2-way user connections such as Video-conferencing, which
requires both users to run special software.
 |
- To allow unrestricted access, the Firewall in this device is
disabled, creating a security risk.
- You should use this feature only if the "Special Applications"
feature is insufficient to allow an application to function correctly.
- This feature should be turned ON only when required.
Use the Advanced Internet Features screen to enable and disable
this feature.
|
This screen can be reached by DMZ host from the Firewall Setting in
Advanced Features screen. An example screen is shown below.

can be entered in the Run dialog, as follows:

LAN Port screen of this device.
