DMZ Host
Figure 42. DMZ Host
Usually all PCs connected to the BroadGuard are protected from Internet intruders
by a built-in firewall. For some kinds of Internet applications, for example,
Internet interactive games, video-conferencing, VPN (Virtual Private Networks), or
as an e-mail server etc., computers must be exposed to the Internet. The DMZ
Host function assigns one of the client computers to be exposed.
BroadGuard setting: You must assign a static IP address to the Client PC to be
exposed to the Internet, then click Save to make the setting effective. Click Restart
to initialize the BroadGuard with the updated settings.
Once the static IP address is assigned to a specific client PC, you MUST specify
the PC as the DMZ Host.
DMZ Host Disable
For extra security, when you do not require the DMZ Host to be exposed to the
Internet, you should disable this function by entering a 0 (zero) in the Client PC (IP
Address) box.
Note: The DMZ PC operates outside the protection of the BroadGuard’s built-in
firewall. If the DMZ PC is not operating in the DMZ role, but is still powered-on
for local use, you should disable DMZ Host to prevent hackers from accessing the
PC.
