Is "WAN" interface mandatory? (3 WAN with VLAN setup)



  • I'm in the process of installing a pfSense router for:

    • One local network (192.168.1.0/24)

    • Three different Internet connections (say: WAN_InternetA, WAN_InternetB, WAN_InternetC)

    As the machine I'm running pfSense on (live from a USB stick for now) only has two network interfaces (em0 and em1) I've plugged the three Internet modems on a switch and created 3 VLANs (VLAN IDs : 2, 3 and 4), one for each modem. My server em1 interface is connected to a tagged port of this switch.
    On pfSense webGUI I've configured the 3 corresponding VLANs and I now have the following Interface setup:

    For now I'm only testing with WAN_InternetA so the other two interfaces are disabled.

    What's bothering me is the "WAN" interface that I have to map to a network port (em1 in the example), however, it is disabled: won't this bring problems?
    In theory I only need 4 interfaces in total : one "LAN" and three "WAN_".

    Thanks for your help on that particular question.



  • You can rename the "WAN" to whatever you want.
    Basically, rename the "WAN" interface to WAN_InternetA and assign it VLAN 2.

    What a possible source of problems in your setup is, that you assigned the parent interface on which VLAN's are assigned.
    –> em1 is directly assigned.
    If you're using VLAN's dont assign the parent interface itself.
    (Just leave em1 unassigned).

    OK, that's what I was afraid of.
    I deleted one of my previous "WAN_x" and renamed/reconfigured "WAN" as the previously deleted.
