On a more sophisticated network, the DMZ (Demilitarized Zone) is a specific area of the network where services are provided in a secure way. However, in Tomato, DMZ has a more simple effect. When enabled, all unknown ports on Tomato's WAN are forwarded to the defined DMZ host IP, instead of each being dealt with individually. Consider DMZ a “lazy” and potentially dangerous approach to port forwarding, due to the large security hole it opens.

Enable DMZ: turns the DMZ function on or off.

Destination Address: is the LAN IP address of the device meant to receive all these forwarded ports.

Destination Interface: is the VLAN/bridge where the above host resides.

Source Address Restriction: if specified, will limit DMZ activity to the defined source IP address range. The Default is empty, which means ports from any IP or range will be forwarded.

Leave Remote Access: If enabled, will force SSH (TCP port 22) and HTTP (TCP port 443) traffic to always be answered by the router, regardless of DMZ settings.
