Double traffic on vlan interfaces "out" side
Tested on amd64 arch version 2.1 with vlans over aggregated and single interfaces. The stats show that the traffic over the lagg is the sum of the interfaces, the traffic shown thru the vlan is doubled in the out direction. The same is with vlan on a single interface. It's not a bug in the web interface graphs as reported in the forum : http://forum.pfsense.org/index.php/topic,67295.0.html you can see the same thing watching the interfaces stats from console : systat -ifstat 1.
