Question
How to create a VLAN for guest internet access
Experts,
We have an HP ProCurve 5412 swtich and 3 Cisco 2800 routers. We also have a main branch which needs to supply non-employees internet access from time to time. Our main brach is on a 10.10.x.x network which connects to a CoLocaton on a 10.11.x.x network then goes to to the internet. I would like to create a VLAN on our 10.10.x.x network so that we can grant internet access to non-employees but they will not have access to any other network resources. I know this possible with our equipment but I have no idea how to implement this. Can anyone help me?

Those sites explain VLANS pretty well.. I actually gotta jet for now but I should be able to get back to u later in the week.. hopefully someone else can jump in to help until then..
Those articles helped out a lot. I think I've got the switch part figured out. As a test I put one port in a new vlan then I tagged another port on both vlans. When I connected the router to the shared port then there was no network traffic flowing from the switch to the router. Do I need to configure the router with 2 sub-interfaces for both vlans to get connectivity.
Please someone look at the attached screen shot and let me know if I have the switch configured right.

VLAN Config screen shot
Ok, thanks for the info jburgaard. That fixed my problem with the main network not being able to access the router. Now I have both vlans up and running. However, there is one snag. the vlan for public use (vlan_guest) is able to access my entire network. How do I block access to the 10.10.x.x network and to the 10.11.x.x network from the public network?

You will need to setup the VLAN on the switch, by identifying the names of each VLAN and which switchports belong to which VLAN.
You will need to setup a trunk port on the switch that goes back to a router.
You will need to setup subinterfaces on the router for the interface that is connected to the switch, and then setup proper routing.
I cannot give you the exact code/buttons to push on your devices since I do not know how your current configuration is setup, but those are the essential steps.
