New to Mikrotik routers. I am preparing a setup on the 2011UiAS with 2 WANS with faiolver and the rest of the ports available for the local network (bridged).
I am not sure how many of the 1G ports I would be requiring but after reading this entry (http://goo.gl/WvUURd) about port group chipsets I was intending to move the WANs to eth6-7 as this would all be connected to VDSLs of up to 30Mb that would connect at 100Mb. By doing this I was hoping to liberate as many 1G ports as possible (5) for local network traffic.
Now I am in doubt that since the main use is routing internet traffic this could have a penalize in performance as I understand it would all mean "software" CPU traffic.
Considering 3x 1Gb ports might be enough in my case, would I be better off leaving WANs on eth1-2 so most traffic remains on the same "side" and through the best router chip?

Wan-lan traffic goes always thru cpu. Does not matter which port you select.
