Chapter 2: Hardware Installation

2.1 Installation Requirements

Before installing MH-2K/4K, make sure your network meets the following requirements.
- Mechanical Requirements
MH-2K/4K is installed between your Internet connection and local area network. You can place it on the
table or rack, and locate the unit near the power outlet.
- Electrical Requirements
MH-2K/4K is a power-required device, that means, it will not work until it is powered. If your network PCs
will need to transmit data all the time, please consider use an UPS (Uninterrupted Power Supply) for your
MH-2K/4K. It will prevent you from network data loss. In some area, installing a surge suppression device
may also help to protect your device from being damaged by unregulated surge or current to the
MH-2K/4K.
- Network Requirements
In order for MH-2K/4K to secure your network traffic, the traffic must pass through the device at a useful
point in a network. In most situations, MH-2K/4K should be placed behind the Internet connection device.

2.2 Operation Mode

MH-2K/4K DMZ port supports three operation modes, Disable, NAT and Transparent. In Disable mode, the
DMZ port is not active. In transparent mode, MH-2K/4K works as proxy with forward DMZ packet to WAN
and forward WAN packet to DMZ. The DMZ and WAN side IP addresses are in the same subnet. In NAT
mode, DMZ side user will share one public IP address of WAN port to make Internet connection. Please
find the following two pictures for example.
