Re: DHCP Server FWF-60d
DHCP works via broadcasts. I wouldn't be too surprised if that would drain the CPU if used across a software switch.
Software switch: just don't use it.
I know, you can bridge a WiFi subnet with the LAN, resulting in a common address space. Looks nice, but it isn't really necessary. Routed WiFi works as well. And maybe you can drop the software switch then.
