VLANs with pfSense, Unifi, and VMware ESXi

For setting up VLANs in my home network I basically followed the tutorial from Crosstalk Solution on YouTube:

The result, however, was not working as expected. As it turned out the critical difference was that I have my pfSense firewall running virtualized on VMware ESXi 6.5. By default the latter “removes” VLAN tags.

But it is very easy to change this and not even a reboot is required. So here are the steps you need to perform:

  • Log in to the admin web UI of ESXi
  • Go to the network port groups and open your internal network
  • Open settings for internal network
  • Change VLAN to 4095
  • Save change

That’s all 🙂
