@aj37 -- I didn't see a difference between bridged and non-bridged mode or if there was it wasn't noticeable.
That is my point. Without NAT-ting, the router will have less "work" to do, and should transfer packets SLIGHTLY faster.
To be measurable, you need an ultra-fast connection with Shaw Residential (1.0 or 1.5 Gbps) or Shaw Business (2.0 Gbps) to "load" the router, and you need a huge number of wired/wireless connections on your home network, each needing NAT-ing, to notice any SLIGHT difference in the performance of the Shaw router.
