SG PCI Appliance Quick Setup

Unpack the SnapGear unit

Check that the SG CD is included with your appliance:

On the SnapGear unit is a single 10/100 network port, a Reset button, and four LEDs

(lights). The LEDs provide information on the operating status of your SnapGear unit.

The two LEDs closest to the network port indicate network link and network activity.

The two LEDs furthest from the network port indicate Power and Heart Beat. The Heart

Beat LED blinks when the SnapGear unit is running. The Power LED is ON when power is applied.

Install the SnapGear unit in an unused PCI slot

Power off your PC and remove its cover.

Select an unused PCI slot and insert the SnapGear unit.

Power on your PC.

Install the network driver on your PC

The SnapGear unit is automatically detected and the appropriate driver is installed when

Windows starts up. It is detected as a Realtek RTL8139-series Fast Ethernet Adapter.

Note

You can check that a new network adapter has been installed by clicking Start >

(Settings >) Network and Dialup Connections > Local Area Connection (possibly followed by a number) > Properties and ensure the adapter is listed in the Connect

using field.

Getting Started

Set up your PC to connect to the web management console

Note

The following steps assume you want to set up your SnapGear unit in bridged mode, so that it sits between your PC and the LAN, transparently filtering network traffic.

If you want to set up your SnapGear unit for NAT mode or to connect directly to your ISP,

refer to Network Address Translation (NAT) on page 148.

The SnapGear unit ships with initial network settings of:

IP address:

Subnet mask:

192.168.0.1

255.255.255.0

Next, modify your PC’s network settings to enable it to communicate with the SnapGear unit.

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

Right-click on Local Area Connection (or appropriate network connection for the newly installed PCI appliance) and select Properties.

Select Internet Protocol (TCP/IP) and click Properties.

35

Getting Started

Select Use the following IP address and enter the following details:

IP address:

Subnet mask:

192.168.0.100

255.255.255.0

Leave the Default gateway and DNS server addresses blank.

Set up the SnapGear unit’s password and network connection settings

Launch your web browser and navigate to 192.168.0.1.

Select Network Setup from the Networking menu.

A login prompt is displayed. Enter the initial user name and password for the SnapGear unit:

User name: root

Password: default

Note

If you are unable to connect to the management console at 192.168.0.1, or the initial user name and password are not accepted, press the Reset button on the SnapGear unit’s rear panel twice, wait 20 – 30 seconds, and try again.

Pressing Reset twice within 2 seconds resets the SnapGear unit to its factory default settings

Enter and confirm a password for your SnapGear unit. This is the password for the user

root, the main administrative user account on the SnapGear unit. It is therefore important that you choose a password that is hard to guess, and keep it safe.

Note

The new password takes effect immediately. You are prompted to enter it when completing the next step.

In the row labeled Bridge, click the Modify icon.

Note

The purpose of this step is to configure the IP address for the web management console.

For convenience, this is generally a free IP address on your LAN.

‘ If your LAN has a DHCP server running, you may set up the SnapGear unit and your

PC to obtain their network settings automatically. Proceed to Automatic configuration.

‘ Otherwise, you must manually specify network settings for both the SnapGear unit and your PC. Proceed to Manual configuration.

Automatic configuration

Before continuing, ensure your DHCP server has two free leases. One is used for the web management console, the other for your PC.

Note

It is strongly recommended that you reserve the IP address to be used by the web management console using the SnapGear unit’s MAC address. In bridged mode, this is the top MAC address of the three displayed on the SnapGear unit itself.

Getting Started

37

Check DHCP assigned. Anything in the IP Address and Subnet Mask fields is ignored.

Click Update.

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

Right-click Local Area Connection (or appropriate network connection for the newly installed PCI appliance) and select Properties.

Select Internet Protocol (TCP/IP) and click Properties and click Properties.

Getting Started

38

Check Obtain an IP address automatically, check Obtain DNS server address

automatically and click OK.

Attach your SnapGear unit’s Ethernet port to your LAN’s hub or switch.

Quick setup is now complete.

Manual configuration

Ensure you have two free IP addresses that are part of the subnet range of your LAN, and ensure you know your LAN’s subnet mask, and the DNS server address and gateway address used by PCs on your LAN.

Note

Contact your network administrator if you are unsure of any of these settings.

The first IP address is used by the web management console.

Getting Started

39

Enter this address as the IP Address, and the subnet mask for your LAN as the Subnet

mask.

Ensure DHCP assigned is unchecked.

You may also enter one or more DNS Server(s) and a Gateway address to be used by the SnapGear unit, not your PC, for access to the Internet. Typically this is not necessary, as only your PC needs to access the Internet.

Click Update.

Next, configure your PC with the second IP address in the same manner you would as if it were connected to the LAN with a regular network interface card.

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

Right-click Local Area Connection (or appropriate network connection for the newly installed PCI appliance) and select Properties.

Select Internet Protocol (TCP/IP) and click Properties.

Getting Started

40

Enter the following details:

… IP address is the second free IP address that is part of your LAN’s subnet range.

… Subnet mask is you LAN’s subnet mask.

… Default gateway is your LAN’s default gateway IP address.

… Preferred DNS server is the IP address of the DNS server used by PCs on your

LAN.

Click OK.

Attach your SnapGear unit’s Ethernet port to your LAN’s hub.

Quick setup is now complete.

Disabling the reset button on your SnapGear PCI appliance

For convenience, the SnapGear unit ships with the rear panel Reset button enabled.

This allows the SnapGear unit’s configuration to be reset to factory defaults.

From a network security standpoint, it may be desirable to disable the Reset switch after initial setup has been performed. This is accomplished by removing the jumper linking

CON2 on the SnapGear unit. This jumper is labeled Remove Link to Disable Erase.
