VLAN Tagged vs Untagged. What does this mean.
I have two interfaces 1 and 2 and decided to use 1 for internal traffic and 2 for external traffic. Both Vlan and untagged. Should one be tagged or not. I don’t see any communication from the External vlan TCPDump . I don’t get any communications TCPDump on the external vlan arp. What exactly does this mean.
