A DMZ can be used to allow all ports (that have not already been specified in other Port Forwarding Rules) to be forwarded to a specific IP Address, such as a computer, another Routing device, etc.
BEFORE CONTINUING: A DMZ will only work when the device that you are planning to point the DMZ to has a Static IP Address.
Please follow the instructions located on this webpage:
If the default IP Address of your modem is 192.168.1.1, then you will need to set the following Static IP Address:
- IP Address: 192.168.1.x (x being a number between 2 and 254 that is not currently being used by another device.
- Subnet Mask: 255.255.255.0
- Default Gateway: 192.168.1.1 (this is the IP Address of your modem)
- Primary DNS: Can be aquired from your ISP (can use 184.108.40.206 instead)
- Secondary DNS: Can be aquired from your ISP (can use 220.127.116.11 instead)
- Open your web browser.
- Type the default IP address http://192.168.1.1 and press Enter.
- Enter the NB1 Username and Password.
NB1 default user name is 'admin' and the password is 'admin'
(Both username and password are case sensitive on these units).
Once Logged in:
- Click Advanced Settings.
- Click Advanced, then Port Forwarding.
You may receive an error message stating you have not setup a LAN Client yet. If you haven't already added a LAN Client, you will need to do so.
