Ok, changing the gateway makes it possible for me to see and access the HDA on my network. Now I just need to change the settings in the Amahi control panel online, which I can't quite figure out how to do.

Ok, so I think the problem is that my HDA wants to be on 192.168.0.10, but my router will only accept IP addresses that begin 192.168.1.

So how do I change the IP addresses in the HDA setup?
