===== DMZ Setup =====

A DMZ (De-militarized zone) is an option for our NAT Configured radios on ePMP

The purpose of a DMZ is to forward port traffic to a customers router, where the router will then pass along the port traffic to the correct device on their network.

Reasons to set up a DMZ include:

  * Double NAT error on PS4/Xbox
  * Most home security systems/IOT devices
  * Advanced networking a home user wants to do

To set up a DMZ, log into the customers CPE and take the following steps:

  * Click on Monitor -> Network
  * Copy the MAC address and note the IP address of their router
  * It will show up as  LAN
  * NOTE: If you see multiple devices on the LAN, they most likely have a switch or their router is not in router mode. Have them fix this accordingly for DMZ to work properly.

  * Once the MAC address is copied, click on Configuration -> Network
  * Make sure the DMZ is enabled and type the IP address of their router
  * NOTE: It will be a 192.168.199.X address, other ranges will not work
  * The range should start on 192.168.199.2

  * To ensure the IP address handed out by our CPE does not change, go to Configure -> Network
  * Look for "Ethernet Interface" 
  * Paste the MAC address of their router, set the IP to what the DMZ is set to and name is "CustomerRouter"

**BE SURE TO SAVE ALL YOUR CHANGES TO THE CPE**

A reboot will not be required
