Need separate access to internet via T1 line using Wireless Router

What would be the best way to setup wireless access to the T1 line to isolate this internet connection from the business network?  

The administrator is asking for access to the internet that is not filtered by the current firewall settings which excludes the YouTube site (educational enironment).  

I have a Windows Server 2003 environment.  In utility room a T1 line connects to a Netgear Router Prosafe VPN Firewall Model FVX 538 with a WAN1 .   The T1 line plugs into WAN1.   The buildings are hardwired to a patch panel and then connected to a switch and plugged into the Netgear Router Prosafe Firewal.  I have a wireless router in the computer lab, but that is plugged into the LAN Network.

You would have to put the T1 on it's own switch...then plug the wireless into that switch and the prosafe into the switch as well and run 2 seperate IP addresses from the T1.

This is the only real way that I could see you segregating the network using what you have now.

The only other way would be to use VLAN's but I don't see that working with the Netgear Prosafe that you have now.

Hi gerdawg,
Thank you for the info.  I just talked to my T1 provider for I was thinking they could provide the actual IP address which they could not.   Since I'm not very versed on this could you provide steps for doing an audit for IPs addresses.  I need to find out which ones are in use now and I know my range is 162-174. I think the one the network is presently using is 192.168.1.161 as gateway.  Thank you.

There would be no real way to find out what IP addresses the ISP assigns you (unless your only using DHCP from them anyway) other than likely the one your already using now (should be setup in your current netgear router).

What you would need to do is find out if the ISP even gives you IP addresses and if so what are they. You would then setup the other wireless AP as a "secondary" network device that is completely outside of your original network configuration. It sounds like this is what they wanted. To do that however you would need another IP address assigned by your ISP and only they can provide you with what that information is.

The IP addresses that you gave me are internal IP addresses .....what you are looking for is an external IP address which is provided by your ISP.
