We have an ASA and need to find a way to disable ARP security on the inside interface. We are going to put a device in front of it that is a sort of nearly-transparent proxy, but it unfortunately rewrites packets that travel through it with its own MAC address. The ASA seems to not like this very much at all.
Is there a way to disable that function? I have no idea what the command would be. The only thing I found related to this was ARP inspection, but that didn't seem to have anything to do with the dynamic ARP cache. It seemed to only be relevant when you have static ARP entries.
Regardless, it doesn't look like we have that turned on, anyway.
