Configuring the Gateway
23
Allowing all applications (DMZplus)
DMZplus is a special firewall mode that is used for hosting applications. When in the
DMZplus mode, the designated computer:
•
Appears as if it is directly connected to the Internet.
•
Has all unassigned TCP and UDP ports opened and pointed to it.
•
Can receive unsolicited network traffic from the Internet.
Use DMZplus mode with caution. A computer in DMZplus mode is less secure
because all available ports are open and all incoming Internet traffic is directed to this
computer.
1. Open the gateway home page at http://192.168.1.254.
2. Click the
Settings
tab, then click the
Firewall
tab.

4. Select the computer that you want to put in DMZplus mode.
If the computer you want to select is unlisted because it is powered off and the
Hide inactive devices option is enabled, you can select it if it is on the same
network and you know its IP address. Enter the IP address and click
Choose

7. Confirm that the computer you selected is configured for DHCP. If it is not,
configure it for DHCP. See “Configuring DHCP” on page 20.
8. Restart the computer. When the computer restarts, it receives a special IP address
from the gateway and all unassigned TCP and UDP ports are forwarded to it.
To stop DMZplus mode on a particular computer, select it and then select
