CHAPTER
ONE
OUT OF THE BOX
1.1 Getting Started
The basic firewall configuration begins with connecting the Netgate® appliance to the Internet. The Netgate appliance
should be unplugged at this time.
Connect one end of an Ethernet cable to the WAN port (shown in the Input and Output Ports section) of the Netgate
appliance. The other end of the same cable should be inserted into a LAN port on the ISP CPE device, such as a cable
or fiber modem. If the CPE device provided by the ISP has multiple LAN ports, any LAN port should work in most
circumstances.
Next, connect one end of a second Ethernet cable to the LAN port (shown in the Input and Output Ports section) of
the Netgate appliance. Connect the other end to the computer.

1.1.1 What next?
To connect to the GUI and configure the firewall in a browser, continue on to Initial Configuration.
To connect to the console and make adjustments before connecting to the GUI, see Connecting to the Console Port.
Warning: The default IP Address on the LAN subnet on the Netgate firewall is 192.168.1.1/24. The same
subnet cannot be used on both WAN and LAN, so if the default IP address on the ISP-supplied modem is also
192.168.1.1/24,disconnect the WAN interface until the LAN interface on the firewall has been renumbered
to a different subnet (like 192.168.2.1/24) to avoid an IP Address conflict.
To change an interface IP address, choose option 2 from the Console Menu and walk through the steps to change
it, or from the GUI, go through the Setup Wizard (opens at first boot, also found at System > Setup Wizard) and
change the IP address on Step 5. Complete the Wizard and save the changes.

1.2 Initial Configuration
Plug the power cable into the power port (shown in the Input and Output Ports section) to turn on the Netgate®
Firewall. Allow 4 or 5 minutes to boot up completely.
Warning: If the CPE on WAN (e.g. DSL or Cable Modem) has a default IP Address of 192.168.1.1,
disconnect the Ethernet cable from the WAN port on the Netgate 3100 Security Gateway before proceeding.
Change the default LAN IP Address of the device during a later step in the configuration to avoid having conflicting
subnets on the WAN and LAN.
1. From the computer, log into the web interface
Open a web browser (Google Chrome in this example) and enter 192.168.1.1 in the address bar. Press
Enter.

1.2.1 The Setup Wizard
The following steps will step through the Setup Wizard for the initial configuration of the firewall.
Note: Ignore the warning to reset the ‘admin’ account password. One of the steps in the Setup Wizard is to change
the default password.
1. Click Next to start the Setup Wizard.
Fig. 3: Click Next
2. Click Next after reading the information on Netgate Global Support.
3. On the General Information page, use the following as a guide to configure the firewall.
Hostname Any desired name can be entered. For the purposes of this guide, the default hostname
pfsense is used.
Domain The default home.arpa is used for the purposes of this tutorial.
DNS Servers For purposes of this setup guide, use the Google public DNS servers (8.8.8.8 and
8.8.4.4).
4. Use the following information for the Time Server Information page.
Time Server Hostname Use the default time server address.
Timezone Select the time zone for the location of the firewall. For this guide, the Timezone will be
set to America/Chicago for US Central time.
5. The WAN interface is the Public IP address the network will use to communicate with the Internet. Use the
following information for the WAN configuration page.
DHCP is the default and is the most common type of interface for home cable modems.
Default settings for the other items on this page should be acceptable for normal home users.

6. Configuring LAN IP Address & Subnet Mask. The default LAN IP address of 192.168.1.1 and subnet mask
of 24 is usually sufficient.
Tip: If the CPE on WAN (e.g. DSL or Cable Modem) has a default IP Address of 192.168.1.1, disconnect
the Ethernet cable from the WAN port on the Netgate 3100 Security Gateway before proceeding.
Change the default LAN IP Address of the device during a later step in the configuration to avoid having
conflicting subnets on the WAN and LAN.
7. Change the Admin Password. Enter the same password in both fields.
8. Click Reload to save the configuration.
9. After a few seconds, a message will indicate the Setup Wizard has completed. To proceed to the pfSense®Plus
dashboard, click Finish.
10. A final notification screen will appear with the Copyright and Trademark Notices. Read and click Accept
to continue to the dashboard.
If the Ethernet cable was unplugged at the beginning of this configuration, reconnect it to the WAN port now.
This completes the basic configuration for the Netgate appliance.
