PLANET XRT-501 - Manual (Page 50)

All outgoing traffic from the DMZ PC will be assigned the WAN IP address associated
with it, rather than the shared IP address on the WAN port. Note that ONLY the DMZ
PC will use the WAN (Internet) IP address you enter on this screen.
To use this feature:
Enter an IP address allocated to you by your ISP into the WAN IP address field.
Select the PC to be the DMZ PC for traffic sent to this IP address.
Enable this DMZ.
Note
The "DMZ PC" is effectively outside the Firewall, making it more vulnerable
to attacks. For this reason, you should only enable the DMZ feature when
required.
3.4 URL Filter
The URL Filter allows you to block access to undesirable Web site, and use this feature,
you must define "filter strings". If the "filter string" appears in a requested URL, the request
is blocked.
Enabling the URL Filter also affects the Internet Access Log. If Enabled, the "Destination"
field in the log will display the URL. Otherwise, it will display the IP Address.
An example screen is shown below.
