Set up a vlan to access internet not network

November 7, 2011 at 08:02:36
Specs: N/A
I have a Dell switch setup with 2 Vlan's. Vlan 1 is to the network. Vlan 20 is going to be for wireless access to the internet. How do I configure the switch/router so that Vlan 20 only connects to the internet and not the network? I will later want to have a 2nd SSID that I want to connect to both the internet and network.

if wireless is built into the router you can't vlan it.
You can vlan the wireless if you have a managed switch the wireless is attached to that then goes to a wired router for internet. In this case the port for the router and the port for the AP would be assigned to the wireless vlan.

Thanks for the reply. I should further explain that this is not a home network. I am at a small office, with a Cisco router and Dell switch. Both of course is managed. On the switch, I have ports 40 - 48 for vlan 20, that I only want to access the internet. I plan on putting 6 - 8 Access Points through out the building. Each port its own AP.

vlan 20 would exist on ports 40-48 AND on the port connecting to the router. Port connecting to the router would also have the other vlans needing internet access listed. Be aware some switchs limit the amount of vlans on a port.

So, one of the router interfaces say fa0/2 needs to be connected to say port 40? What about ip addresses? The default gateway on the router is 192.168.1.1. Do I need any other on the switch on Vlan 20?

You would only use the 192.168.1.0 subnet for all.

You only vlan AND subnet in huge installations. No reason to do so at your level
