Hi Dag, Thanks for the response. I am currently looking into VLANs and network configuration for my case. But I want to know one thing: are "untagged" VLAN networks sufficient for an advanced zone to function with two networks? I did not state I do not want to use VLANs for networking but I wanted to know if ACS advanced zone would function if VLANs are untagged? (The network router/switch did not support them). According to my knowledge I would have to dig much deeper into kernel files to provide a dummy interface as systemctl restart network would not function properly, still appreciate the advice. I will look into this more and see what I can do with it.
