That depends, maybe you mean Windows->NAT vs. Windows non NAT. I 
think there's implications
in router, unless your assuming NAT.

As well, pvlans are prone to fail if not a forethought of 
architecture instead of
an after effect. Trying to put legacy networks into a pvlan 
architecture is like
putting square pegs in round holes.

My experience has been pvlans cause more trouble than they are worth.
