Interfaces

OPNsense allows you to set up Interfaces, which can be used to set up separate networks. I set up 2 interfaces to allow my homelab to operate on 1, and all other devices (including my roommates) to operate on the other. The Interface assignments are as follows:

  • igb0 = Port 1 of my NIC, which is connected directly to my Eero Mesh Router
  • igb1 = Port 2 of my NIC, which connected to an 8-port gigabit switch, for my homelab
  • igb2 = Port 3 of my NIC, which is my WAN connection from my modem to my OPNsense machine
  • igb3 = Port 4 of my NIC, which is currently open and not connected to anything.
