<div>
normally I would have several vlans within my network like this:<br />
<br />
internal_data<br />
internal_voice<br />
dmz_data<br />
external_data<br />
<br />
so internal data and voice are for internal pcs and servers and are terminated at a firewall's internal interface<br />
dmz vlan would contain dmz servers and firewall's dmz interface<br />
external vlan would contain ISP link and firewall's wan interface.<br />
<br />
so I would suddenly being asked to provide clear internet to a specific pc, then I would configure one more port in external vlan and plugged that PC into that port.

Do you have any example configs for me to look at. &nbsp;Do you not need any acl to be sure that data cannot pass between the vlans?

I am using HP Procurve switches on my network. &nbsp;I have multiple vlans for data as well as voice. &nbsp;I am installing a new 8212 core switch and I need to get public internet access from our datacenter on the third floor to a division on our first floor. &nbsp;What is the best way to get this connection to the location using our infrastructure. &nbsp;My guess is to use an ACL but I am not really sure where to start. &nbsp;I need to be sure nobody using this public network has any type of access to our corporate network. &nbsp;Suggestion or examples would be very helpful.

Network design and methodology, also known as network architecture, is the design of a communication network. It is a framework for the specification of a network's physical components and their functional organization and configuration, its operational principles and procedures, as well as data formats used in its operation. In telecommunication, the specification of a network architecture may also include a detailed description of products and services delivered via a communications network, as well as detailed rate and billing structures under which services are compensated.

Network Architecture

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.
