Does anyone know exactly how the 'Enable HW Accelerator' option (under the 'LAN' tab comes into play? From reading the other threads, I was under the impression that the option primarily provides some advanced cut-through/cache type switching functions to minimize kernel level inspection of traffic moving *between the LAN/WAN*. Obviously it has to be disabled for things like QOS because it now has to go through kernel level inspection for rule matching etc. What I cant figure out is why this option seems to be interfering with local LAN clients - in my case a 2.4Ghz wireless client (PS Vita) to a wired client (PS4). With the accelerator option enabled it experiences persistent timeouts, drops connections etc - but when I explicitly disable it, everything runs without a hitch. Theres no traffic (from what I can see with wireshark) that is leaving the local wifi->LAN switch subnets, so I'm curious about where it comes into play - ie. is it route based, or is it always coming into play between virtual switches (i.e. between wifi and LAN, LAN and WAN, wifi and WAN - but not between LAN-LAN, wifi-wifi etc).
