Cisco 3640 configuration

[Milbr821]

I am realatively new to networking. At work we have a lab, which we use for testing and learning purposes. The lab consists of a windows 2003 server(domain controller), Red Hat linux 9.0, win2k, win nt, and a cisco 3640 router. Our lab is not on the internal network for security reasons. Our networking administration installed a wireless router to allow individuals in meetings to access the internet. My goal is to give the lab internet capabilities using the wireless conection. I want the lab to simulate a real lan environment as much as possible. To do this I purchased a netgear wireless ethernet bridge and connected it to our cisco 3640 router, which is then going to distribute the internet connection to the rest of the computers. The wireless router is assigning ip address dynamically. I have the wireless bridge set up to obtain an ip adress automatically. The default gateway for the bridge is 192.168.1.1. The bridge is then connected to the fastethernet2/0 port on the cisco 3640 router. That port on the router has an IP address of 192.168.0.201. the router is then connected to a hub through the ethernet0/0 port with an IP address of 10.0.0.1. The windows 2003 server has an IP of 10.0.0.2 and gateway of 10.0.0.1.

Wireless bridge-->fa2/0-->eth0/0-->hub

When connecting to the wireless network using a laptop, you are automatically redirected to a web page with ip address of 192.168.0.1. This page was created by our network guys and has a button for the user to click to connect to the internet. When using the setup in the lab and trying to access the internet, you are not automatically redirected to this page. If i type in the ip address 192.168.0.1, I get the connection screen and even though it says i am connected, I am not able to view any web pages. I have tried configuring the router many different ways. I think that I need to enable dhcp, but I am a little lost when it comes to creating dhcp pools.

I am sure there are lots of errors with my current setup. Any direction or advice will be greatly appreciated. Thanks!!

At the top you say:

"Our lab is not on the internal network for security reasons. "

If you connect the wireless, you will be putting the Lab on the Production network, which you say is a bad thing.

Maybe if you put in another wireless bridge in the Production network's DMZ you could get away with it (with the Production network admin's permission .. otherwise your job could be at risk).

Chances are you need to go through a proxy / capture portal to get out; they will need to set that up for your Lab network to participate.

Good Luck

The wireless connection is not connected to the internal network. It was set up to strictly provide Internet access and nothing else...so I know its not going through a proxy portal. Any other ideas?

You first have to make sure that the router can get to the internet first, before you go any further.

Logon to the router and ping something like microsoft.com.

If you can ping from the router that means there is a configuration problem; It could be multiple things. But first try the ping and give me the results.

You might need to use a cross-over cable to connect the wireless to the router.
