Security Gateway Manual SG-1100
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 WebGUI, 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®

Warning: If your DSL or Cable Modem has a default IP Address of 192.168.1.1, please disconnect the Ethernet
cable from the WAN port on your SG-1100 Netgate Security Gateway before proceeding. You will need to change
the default IP Address of the device during a later step in the configuration.
