Question: Does an Aruba campus AP work through a NAT or PAT device?
Product and Software: This article applies to all Aruba platforms and ArubaOS versions.
An Aruba campus access point (AP) is defined as an Aruba AP that is connected via Ethernet to the same network infrastructure (the Intranet) as an Aruba controller.
Whether the NAT device is a Port Address Translation (PAT) or what is known as many-to-one NAT or a one-to-one NAT, the campus AP functionality of an Aruba AP is not supported.
In some situations, like the one-to-one NAT and possibly some ArubaOS versions, it may seem that the campus AP comes up on the Aruba controller.
However, Aruba cannot guarantee its operation throughout ArubaOS code upgrades and does not support such APs.
A campus AP requires a direct L2/L3 IP connectivity to an Aruba controller.
The remote AP (RAP) functionality of an Aruba AP is not considered a campus AP functionality. This article does not apply to RAPs.
