CyberGuard SG Rack Mount Appliances

Set up a PC to Connect to the Web Management Console

The CyberGuard SG appliance ships with initial, static IP settings of:

IP address:

192.168.0.1

Subnet mask:

255.255.255.0

Note

Initial configuration is performed through a port on network switch

A

(

A1

–

A4

).

All other

interfaces are by default inactive, i.e. there are no network services such as DHCP in

operation, and no IP address is configured.

If you attach

A1

–

A4

directly to a LAN with an existing DHCP server, or a PC running a

DHCP service, before performing the initial setup steps described below, it will

automatically obtain an additional address.

Your CyberGuard SG appliance will still be

reachable at 192.168.0.1.

The address you use when navigating to the unit (as described

Set up the CyberGuard

SG appliance's password and LAN connection settings

) will be used as the CyberGuard

SG unit’s LAN interface address and the other will be discarded.

Your CyberGuard SG appliance will need an IP address suitable for your LAN before it is

connected.

You may choose to use the CyberGuard SG appliance’s initial network

settings as a basis for your LAN settings.

Connect the supplied power cable to the power inlet on the rear panel of the CyberGuard

SG appliance and turn on the rear panel power switch.

Connect one of the ports of network switch

A

(

A1

–

A4

) directly to your PC’s network

interface card using the straight through cable (blue).

Next, you must modify your PC’s network settings to enable it to communicate with the

CyberGuard SG appliance.

Note

It is recommended that you perform the initial setup steps with the CyberGuard SG

appliance connected to a single PC only.

However, you may choose to connect the

CyberGuard SG appliance to the LAN before completing the initial setup steps.

Before doing so, it is critical that you ensure there are no other devices on the LAN

with an address of 192.168.0.1

Use the straight through cable (blue) to connect the CyberGuard SG appliance to your

LAN’s hub.

Next, you must modify your PC’s network settings to enable it to communicate with the

CyberGuard SG appliance.
