I have been working on a new network design. As part of the design I am using VLAN's to separate traffic. I want to create a special VLAN for true public IP addresses with no NAT'ing. The reason for this is in some cases vendors bring demo equipment in which requires public IP's with no NAT. I am a little puzzled how to create a public VLAN internally to achieve this. Does anyone have any suggestions on how to do this? Ideally when configured I will be able to switch any port to the public VLAN.
