I hope someone can give me a basic pointer here. I'll try to be as detailed as possible but I'm asking this for a third party. They use an 800 series controller with ArubaOS v5.0.3.3 with a number of Aruba APs attached, in a corporate environment with a number of WLANs already configured. Their controller was installed years ago and was managed by someone who has now left the company, and I have no access to a controller so I'm trying to work this out theoretically.
I've scanned through the Aruba OS documentation for version 5, and spent a while perusing the boards. I think the following *may* be possible.
What I'm trying to find out is: can a NAT/DHCP appliance be plugged into a physical port on the controller to allow devices associated to a particular WLAN to get DHCP from this external device and therefore use it as their default gateway. i.e. Can I create a WLAN with a simple SSID and encryption profile but no authentication profile/server/method, create a VLAN, assign both a physical access port and my WLAN to this VLAN, plug the appliance into the port and expect to see layer 2 traffic passing from a user device to the appliance? If so are there any gotchas I would need to be aware of?
I've become unstuck particularly working out if I can assign just a simple SSID profile to a WLAN, and no security/authentication/AAA profiles: basically will the controller allow me to create a simple layer 2 broadcast domain and act as a layer2 switch for my traffic.
Any help most welcomed.
Cheers.
