User's Manual
Appendix B. 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 "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 selecting Exposed Computer from the Advanced
Internet Features screen. An example screen is shown below.
Figure 1: Exposed Computer

Where IP_Address is the IP Address shown the External LAN Port
screen of this device.
