Technicolor TG589 router - DMZ host

The Technicolor TG589 router allows you to configure one local device as a De-Militarized Zone (DMZ) host. This means that:

  • none of the Technicolor TG589 router firewall rules will be applied to this device
  • all traffic originating from the internet will be forwarded to this devices unless there is a specific port forwarding rule defined or automatically created for a specific type of traffic

Use a static address for the DMZ host

Make sure that your DMZ host uses a static IP address (you choose a fixed IP address) instead of a dynamic IP address (the DHCP server assigns an IP address). If you use a dynamic IP address, the device might get a new IP address after some time and the port forwarding rule will no longer be applied to the device and another device may unexpectedly be acting as the DMZ host.

How to configure a device as DMZ host

  1. Browse to the TG589 router web  interface.
  2. Select WAN Services. The WAN services page appears.
  3. In the upper-right corner, click show advanced. The DMZ section appears.
  4. Switch Enabled to .
  5. In the Destination box, type the IP address of the device that you want to use as the DMZ host.
  6. Optionally, you can make exceptions on the DMZ by creating port mappings to direct specific traffic to other devices. To do this, click Add new port mapping under Port forwarding table.
  7. Select Save. DMZ is now active.
