Enabling the DMZ feature in a Linksys wireless router

The Demilitarized Zone (DMZ) is a feature that allows only one (1) local user to be exposed to the Internet for special purposes like Internet gaming or video conferencing.   

IMPORTANT:  Below is the list of things to remember when enabling the DMZ feature in your Linksys router.
  • You can either use the computer’s MAC Address or IP Address when setting up DMZ.
  • If you decide to use the IP Address, be sure to set up a Static IP Address to the computer that you want to expose because its IP Address may change when using the DHCP function.  For instructions, click here.
  • If your router has a DHCP Reservation feature, you may also use it instead of setting up a Static IP Address on your computer.  Click here for further information regarding this. 
 To enable DMZ, follow the steps below:
Step 1:
Access the router’s web-based setup page.  For instructions, click here.
NOTE:  If you are using a Mac® computer to access the router’s web-based setup page, click here.
Step 2:

Step 3:
Click DMZ.



Step 4:
Select Enabled and set the Source IP Address and Destination.

  • Source IP Address - If you want to allow any IP Address to access the exposed computer, select Any IP Address.  If you want to allow a specific IP Address or range of IP Addresses to access the exposed computer, select the second option and enter the IP Address or range of IP Addresses in the fields provided.
  • Destination - Enter the IP Address or MAC Address of the computer you want to expose.  If you want to specify the DMZ host by IP Address, select IP Address and complete the IP Address in the field provided.  If you want to specify the DMZ host by MAC Address, select MAC Address and enter the MAC Address in the field provided.
NOTE:  To retrieve this information, click the DHCP Client Table button to show the list of all wired and wireless computers and devices connected to the router.


For WRT- and BEF- routers, you only need to select Enable and enter the DMZ Host IP Address.
