A home router DMZ (demilitarized zone) host is a host on the internal network that has all UDP and TCP ports open and exposed, except for those ports that have been forwarded. This is used as a simple method to forward all ports to another NAT device or firewall. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN): an external network node can access only what is exposed in the DMZ, while the rest of the organization's network is firewalled.
Mercku's M2 and M6 DMZ host solves issues where the external network cannot access the internal network server after installing a firewall and sets up a buffer between the non-secured system and the secured system. The DMZ is typically a filtered subnet that establishes a safe zone between the internal and external networks and allows you to only expose one device to the internet.
DMZ host features can be accessed through the Mercku App or Portal.
Make sure you assign a static IP address to the device that you want to become the DMZ Host. This is important so that your router does not assign a random IP to a device that you don’t wish to be the DMZ host.
The management route is the same on both the Mercku M2 and the Mercku M6.
