Hello, I own one of these and already flashed it with the DD-WRT. But the only very interesting thing it does not do yet is port mirroring. The chip that I think is inside, is Broadcom 5325e and the specs for it clearly state that it is capable of port mirror. Here is a link to the BroadCom website. On this page right hand side there is a link to the specs in pdf: http://www.broadcom.com/products/Sma...ducts/BCM5325E Regards!
