VLAN on interface aliases

  • Hi there,
    just before evaluating pfSense I'd like to clear some questions in my mind:

    • Does it support VLAN tagging on interface aliases?
    • Whether the above is not possible, can I assign multiple VLANs on a single NIC and assign the relative VLAN IPs? (like in the dot1q linux driver)
    • Can I put pfSense between 2 VLANs and filter the traffic between the vlans?

    All of this would be great to know.

    Thank you for your help.


  • pfSense doesn't support interface alias in version 1.0, however this is already present in head.

    You can add multiple VLANs to a physical interface. Each VLAN will become a seperate interface providing all the options/services you have for a real physical interface (unique IP/subnet, filtering, dhcpserver, …).
