Bear with me on this one. I have two Airport Extremes at home linked via a long gigabit ethernet cable. I wanted to improve the control over the network by connecting all my devices via smart gigabit switches to enable QOS, priority, aggregated links on some devices etc.
Now what I was wondering is - in this scenario, all the heavy lifting would be done by the switches but the Airports would still be the DHCP server giving out LAN addresses. If I have one of the airports and two computers connected to a switch, so they're both on the network with their own IP addresses now and i send a file between both. Would the switch send the data directly between the two computers as if they were wired together by the gigabit cable or would it feed the data through the Airport as its the DHCP device first?
