I may have left out a critical piece of information. The problem is not consistent. I have had the Aruba setup for several months. No clients experienced an issue in the first week or two. Then 2 clients received the incorrect ARP information, then a couple more etc. Now, it is hit and miss while clients are connected. I have already set static ARP entries for the Gateway on all client workstations that regularly connect to the network. However, I can't set static ARP on mobile devices or some of our other network hardware. As I understand it, ARP replies should only come from the device with the assigned IP address unless a device is setup to proxy the ARP for an IP address. I think I am looking for a setting that would cause the Aruba to think it is supposed to be a proxy for the gateway. The only place on the Aruba where the gateway IP address is shown in the settings is for the default gateway. I hope this triggers something for one of you. Thanks again.
