LAN subnet mask: 255.255.255.0
The CyberGuard SG appliance needs an IP address suitable for your LAN before it is
connected. You may choose to use the CyberGuard SG appliance’s initial network
settings above as a basis for your LAN settings.
Connect the supplied power adapter to the CyberGuard SG appliance.
 If you are setting up the SG300, attach your PC’s network interface card directly to
any network port on its LAN switch using the supplied network cable.
 If you are setting up the SG560, SG565 or SG580, attach your PC’s network interface
card directly any network port on switch A (A1 – A4) using the supplied network
cable.
 Otherwise, connect the CyberGuard SG appliance’s LAN network port directly to your
PC’s network interface card using the supplied network cable.
Note
At this point, if you attach the CyberGuard SG appliance directly to a LAN with an existing
DHCP server, or a PC running a DHCP service, it will automatically obtain an additional
address. The CyberGuard SG appliance will still be reachable at 192.168.0.1.
However, we strongly recommend that you do not connect the CyberGuard SG appliance
to your LAN until instructed to do so by this guide.
All other network ports are by default inactive, i.e. they are not running any network
services such as DHCP, and they are not configured with an IP address.
Next, modify your PC’s network settings to enable it to communicate with the
CyberGuard SG appliance.
Click Start -> (Settings ->) Control Panel and double click Network Connections (or in
95/98/Me, double click Network).
Right click on Local Area Connection and select Properties.
