The router box, sometimes referred to as a Cable/DSL router or a Network
Address Translation box (NAT box), is the hardware bridge between two
networks. In this case we are using NAT boxes to put individual internal LANs on
a multi-server LAN or a corporate LAN. SMC makes a device that contains both
the functions of a NAT box with a LAN HUB and it is this device we use.
What you need to set up a NAT box.
1. A NAT box. (part of these systems)
2. A choice made by the customer’s system manager regarding which of the
two possible LANs the system is to be attached to.
3. The following network addresses from the system manager:
A static IP address and mask for the NAT box on the LAN
Possibly two DNS addresses
Possibly two WINS addresses
A gateway address if applicable
4. Two LAN cables
5. A PC or lap top to set up the NAT box
Overview
There are two sides to the NAT box, the LAN side connecting to the systems
internal LAN and the WAN side connecting to either the multi-server LAN or the
corporate WAN.
1. To set up the LAN side connect your PC to a port on the internal LAN side
of the NAT box.
2. Make sure or configure your PC network connection is set to DHCP.
3. Configure the NAT box to the predetermined Fixed IP address of the NAT
box on the internal LAN
Note: This change of address causes the PC to disconnect from the NAT
box.
4. Re-configure your PC to the fixed IP address on the internal LAN.
5. Re-connect your PC to the NAT box and configure the WAN side.
6. Connect the NAT box to the multi-server LAN or to the corporate LAN.
Keep the NAT box’s user manual handy.
Reset the NAT box
It is likely that your NAT box has been configured in manufacturing and
you will have to reset it before following this procedure.
To reset:
1. remove all cables from MBMs and PBMs from the LAN side of the
box.
2. Press and hold the blue reset button for 5 seconds.
3. Wait for reset to complete.
