Access Point 1240AG allowing multiple network traffic

Good afternoon, have a customer site that has some 1240AG Access Points throughout their facility. Each one's software version is 12.3(7)JA2. Each access point is assigned a static IP# of - I can access each via web browser using it's IP (ie ) and see it's configuration settings.

I also have a Windows server with two NICs, one has a 172.16.1.x IP# for hard wired connections and other has a IP# for wireless connections.

Each access point is wired to a standard non-cisco switch. No VLANs have been configured on APs. We are running static IP#s on all devices.

Problem is that the 1240AG(s) are allowing clients that have an IP# of 172.16.1.x access to the network resources, eventhough the access point is setup on a 10.16.0.x network without VLANs. Users were instructed to change their IP#s to the 10.16.0.x network whenever they wanted to use wireless, but most have not since they know they can jump on the 10.16.0x access points using their 172.16.1.x IP#.

I don't want any wireless clients access to AP(s) unless they are on the 10.16.0.x network. I want to force the users to use correct 10.16.0.x IP#s.

Any comments and suggestions appreciated.

Thank you.

Did you connect both server nics to the same switched network or isolate them ? The real question is how did you plan to route from 10.16.0.x to the 172.16.1.x network ? Are you routing through the server or do you have a layer 3 switch somewhere. If you put a switch or router with secondary IPs that would explain the problem. Isolate the 10.16 network and that should fix it.
