How to Install OPNsense on the Vault

Once the OPNsense installation image is properly burned to the USB drive, it is ready to be installed on the Vault.

• Verify the Vault is powered off
• Verify a monitor (or COM cable/serial console) is connected
• Verify the wired USB keyboard is plugged in (ignore if using serial connection)
• While powering up the Vault, hold the <F11> key to open boot options
• Select your USB drive
  • If you see a partition that mentions UEFI, select this one
• OPNsense should now start booting, lots of text will start flying across the screen (don't be scared!)
• Pay attention to the screen until you see a message stating: "Press any key to start the configuration importer" (This message may not show up with some coreboot firmware)
• Press the <Enter> key two times to skip this
• Pay attention until you see a message stating: "Press any key to start the manual interface assignment" (This message and the following few steps may not show up with some coreboot firmware, it may just skip to the login prompt and automatically set WAN to port 2 and LAN to port 1)
• Press <Enter> key
• When asked to configure LAGGs:
  • Type "N" and hit <Enter>
• When asked to configure VLANs:
  • Type "N" and hit <Enter>

This next part is very important. You must manually configure the interfaces so you actually have a WAN and LAN port to use. You should see a list of all the NICs (Ethernet Interfaces) shown on the screen. These will be different (igb, igc, ixl) depending on the NICs found in the Vault. They will be listed in numerical order. The interface ending in 0 is the very first Ethernet port on the unit, which will be signified by "WAN" or "1" or "SFP+1" on the chassis of the Vault. To make this as simple as possible for tutorial purposes, we will configure WAN to be the first Ethernet Port and LAN as the second ethernet port (If you bought OPNsense preinstalled from us, please refer to the chart at the bottom of this article for how we set them up for you):

•  When asked to "Enter the WAN interface name":
  • Type the interface name ending in 0 and hit <Enter>
    • This may be igb0, igc0, ixl0, em0 depending on the Vault
• When asked to "Enter the LAN interface name":
  • Type the interface name ending in 1 and hit <Enter>
• When asked to "Enter the Optional interface 1 name":
  • Press your <Enter> key one time to skip
  • You can setup the other interfaces at a later time by following this guide
• When asked "Do you want to proceed?"
  • Type "y" and hit your <Enter> key
• It will start configuring the interfaces and other features
• You will eventually be prompted with a welcome message and a login
  • Type installer for the login and hit <Enter>
  • Type opnsense for the password and hit <Enter>
• A new installer screen should show up
• Continue with default keymap
• Select Install (ZFS) as the filesystem, hit <Enter>
  • You should select UFS only if you are installing to an eMMC storage device on a V/VP series Vault
• Select Stripe – No Redundancy, hit <Enter>
• Highlight over the SSD by using the arrow keys, and press your SPACEBAR (please, please hit the spacebar key) to actually select the drive. You will see an [*] when the drive is selected. If you do not select the drive you will get an error.
• Hit <Enter>
• If prompted for a "Last Chance!" message, confirm that you want to completely overwrite the contents of your SSD by selecting:  <Yes>
• Allow the installation to complete, reboot the system, unplug the USB drive from the Vault
