I'll make this quick.

I have a Dell 2724, a Windows 2000 Server, a Sonicwall TZ170, and a Netgear Wireless Router.

Currently, the Router connect to the Dell switch, and the server is connected via the switch as well. All workstations see the server, printers, etc. All is well. Here's the goal - Attach the wireless router to allow our clients to connect to the Internet but NOT to our network resources. Would I do this via VLAN? I've been in the field for 16 years. I'm pretty savvy. But this is a bit over my head. I've never had administrative position like I'm in now, so I'm learning as I go.

Thanks!!

create a sub network.

On any ethernet router. You change the routers IP address and its subnet.

And the external IP Subnet.

So, lets say ur office uses 192.168.0.*..

Configure the router to take the 192.168.0.* but to use 192.168.1.* for itself and to lease out 192.168.1.*

Computers on different subnets can not communicate with each other.

So everyone connecting to your wirless should receive IP's of 192.168.1.*-255 and will see ONLY ur wireless router ip as 192.168.1.1

They will not be able to access what behind the wireless router which uses 192.168.0.*-255

I beleive in most basic small routers like the netgear and linksys...you have the options to choose from the options to configure the router

DHCP
Static IP
PPPOe

4 or 5 options....choose the "Static IP"

Wait;...i have a wireless netgear router.. :D

ooooooooooooow

Are you using an "ADSL wireless router"
or an "Ethernet router"

You need to use an Ethernet router....
I have a linksys...so i wont be able to guide u through the exact steps...but this is the scenario.

The office IP scheme is 192.168.1.*. Subnet mask is 255.255.255.0

You're suggesting taking the NetGear router, and configuring IT's IP as 192.168.1.x and making it hand out IP addresses on 192.168.0.*?

Ok. So I configured it that way. It doesn't work. That's why I was wondering if I couldn't do it with a VLAN on the 2724?
