I am setting up a VLAN according to the attached diagram. I am not sure this will work, as the firewall will be at a remote location that receives its internet from my location, BUT I also want direct access to their network at my location. The issue is the ISP connection. I want those ports to be without an IP configuration (HP Procurve IP set to disabled). Do, I have that traffic be tagged. My understanding on Procurves is that I can have one port on a VLAN be untagged traffic.
Previously I had problems with the ISPs ARP tables and these switches if they were not set to IP disabled. So, I want the VLAN attached to the external ports and the ISP to basically be "dumb," but still have the VLAN to the internal network. Please see the attached diagram.
