May be I misunderstand but no need for any tag on same layer 2 network

yes the VMs and the firewall on the same L2 network also the firewall is hosted in oVirt along side the VMs, currently there is no external switch connected to the nic and i would like to know if it is possible to pass tag internally.

Is it what you're looking for?

sorry if i got you guys confused.
for clarity:

i have a server with two nic, currently one nic is connected to public network and the other one is disconnected.

And i have a vm that will be the firewall of other vm inside this standalone/selfhosted ovirt.

then i am figuring out how can i pass the vlan ids on the vm or is it possible.

I think it would fallback to the linux bridge default configuration,
which internally tags untagged frames with vlanID 1, and untags them
when exiting the port. Unless I'm wrong (for instance, we change the
bridge defaults), this means you can pass untagged frames through the
bridge.

Adding Edward, to keep me honest.



I am unsure if I got the problem.
If you connect an untagged logical network to a vNIC (virtual NIC of a VM), all untagged Ethernet frames will be forwarded from the host interface (physical NIC or bond).
If no tagged logical network is attached to this host interface, VLAN tag filtering is not activated and even tagged Frames would be forwarded to the vNC.

Does this answer the question?
