Getting Started

Enter this same IP address as the DNS server IP address to be handed out by the DHCP

server.

Restart all the PCs on the network (this resets their gateway and DNS addresses).

Note

The purpose of restarting the computers is to force them to gain a new DHCP lease.

Alternatively you can use a utility such as ipconfig to release then renew a lease, or

disable and re-enable the network connection.

Quick setup is now complete.

Manual configuration of your LAN

Each PC or other host on your LAN must be configured with an address within the

bounds of the subnet described by the CyberGuard SG appliance’s IP address and

subnet mask. Using the example CyberGuard SG appliance IP address of 192.168.0.1

and subnet mask of 255.255.255.0, each host must be assigned an address within the

range of 192.168.0.2 – 192.168.0.254.

Additionally, each host must designate the CyberGuard SG appliance’s LAN IP address

as their gateway and as their DNS server for Internet domain name resolution.

An example is given below for manually configuring a Windows PC:

Click Start -> (Settings ->) Control Panel and double click Network Connections (or

in 95/98/Me, double click Network).

If presented with multiple connections, right click on Local Area Connection (or

appropriate network connection) and select Properties.

Select Internet Protocol (TCP/IP) and click Properties (or in 95/98/Me, TCP/IP ->

[your network card name] if there are multiple entries).

Enter the following details:

• IP address is an IP address that is part of the same subnet range as the

CyberGuard SG appliance’s LAN connection (e.g. if using the default settings,

192.168.0.2 – 192.168.0.254).
