Installing and physically connecting the firewall

Start with the installation of your firewall. This step will allow you to access its administration interface so that you can configure it.

NOTE
Specific features may vary depending on your firewall model. More information relating to this chapter can be found in the SNS Presentation and installation guide and Quick Installation Guide provided with your firewall.

Installing the firewall

  • Install your firewall in a suitable location, such as a server room or restricted-access office. Use a special assembly system if necessary.
  • Plug your firewall into a power supply unit with the right voltage. If possible, choose a connection to a UPS (uninterruptible power supply) device.
  • Hire a qualified electrician to install models connected to a DC mains supply.

Physically connecting the firewall to a client workstation

  • Use an Ethernet cable to link your firewall's internal port (“IN” in our example) to your client workstation or local network on which the client workstation is connected.
  • The device on which the firewall is connected must be configured to automatically obtain an IP address (via DHCP), or have a static IP address that belongs to the firewall's network 10.0.0.0/8 (except for 10.0.0.254, which is already assigned to the firewall).
  • Do not immediately connect your firewall to your Internet access device. Wait until you have configured the firewall’s network settings.

Starting the firewall

  • Once all the devices are connected, start your firewall.
  • Wait while it finishes its startup sequence. Do not unplug it during this phase.
