Possibility DMZ without network card?

Hello, my setup: the network cables are routed through a 24 port switch to three 8 port switches, where I have set up VLANs on the switches for red and green, the flags are removed on handover to the ipfire in the middle. Data exchange between the switches is done over two redudante ports where flagged traffic goes through. For the simple reason that the modem is in another room and I could not lay a long cable at once. So on two switches one port belongs to another VLAN leading to the red ne…

This was my question to use one network card with two zones and VLANs
I already had red and green configured into VLANs because my modem is located somewhere else like the Ipfire, now the consideration was to run green as native and orange as VLAN, but because I already had green configured as VLAN, it didn’t work because of the tags. When I then made the green zone also a VLAN it worked. What’s wrong with putting the blue network on eth0 and specifying a third VLAN? As long as the ports on the switches cleanly set the tags and remove them again, this should run cleanly.
