[SOLVED] Q-in-Q VLAN

[seed]

I know that OPNsense removed Q-in-Q VLAN support. Reference:

https://github.com/opnsense/core/issues/2078

However i still testet the configuration out of curiosity togehter with vrf-lite:
Since the GUI does not support this the configuration needs to be done in the commandline.

Code: [Select]

    # create vlan Interface on top of physical Interface
    ifconfig vlan1000 create vlandev igb0 vlan 1000 vlanproto 802.1ad up

    # create vlan Interface on top of vlan Interface
    ifconfig vlan42 create vlandev vlan1000 vlan 42 inet 10.5.42.1/24
Removing configuration:

Code: [Select]

    ifconfig vlan42 destroy
    ifconfig vlan1000 destroy

Together with an Interface wich is configured in a second routing table:

Code: [Select]

    setfib 1 ifconfig vlan1000 create vlandev igb0 vlan 1000 vlanproto 802.1ad up
    setfib 1 ifconfig vlan42 create vlandev vlan1000 vlan 42 inet 10.5.42.1/24
Removing configuration:

Code: [Select]

    setfib 1 ifconfig vlan42 destroy
    setfib 1 ifconfig vlan1000 destroy


#Disclaimer: I have not testet this other than commandline setup.

It would be amazing if OPNsense could introduce this feature in the upcoming versions. I know that this is an edge case that will be used by a small amount of users yet it would enable certain setups like Fiber connections that need a vlan that is delivered by the provider. Inside of this vlan one can configure multiple vlans with multiple PPPoE interfaces. Those Interfaces need to be in different Q-in-Q VLANs and Routing tables.
For comparison a setup like that is possible with Mikrotik or Cisco.

Well, the old Q-in-Q was netgraph based and therefore removed. The new one you see is new since OPNsense 22.1 / FreeBSD 13 and a ticket already exists:

https://github.com/opnsense/core/issues/5560

And it's also published on the roadmap.

Thank you for the clarification. I am happy to see how OPNsense has evolved over the past few years.
