Based on your config I have no clue what your are doing.
Vlan filtering typically has one bridge you have two??
Is this device supposed to be acting as a router or a switch?
I suspect a switch because its a switch LOL, and also by ethernet1, I assume that is a trunk port to the upstream router.
IF so, then why is there any DHCP on this device??
Please read the following it has switch case included: http://forum.mikrotik.com/t/using-routeros-to-vlan-your-network/126489/1
