Hi, I have been reading on the forums about Fastnat, and how it essentially breaks QOS and Access Restrictions on Tomato at present. I then randomly read that if QOS is disabled and you have no access restrictions enabled Fastnat should be enabled. This appears to be the case with the Advanced Tomato 1.28.0000 MIPSR2-1.15.14 K26 USB AIO build i have just upgraded my Asus RT-N16 to. With access restrictions / QOS disabled: With access restrictions / QOS enabled: As can be seen i get another 18Mb/s throughput with what i presume is Fasatnat enabled, my connection is 120Mb so is been maxed out. Now to be perfectly honest i'm happy with 108Mb/s, its always been the upload speed i've wanted more of in recent years. My question: If at some point in the future i was to get an Asus RT-AC66U would the throughput be any better without Fastnat? i'm presuming its CPU dependant from what i've been reading here. I have no plans to get another router at present, i'm just curious.
