Question about VLANs and bridges

Hi, I’ve bought yesterday RB951G and currently I’m trying to make another VLAN. From factory configuration I see there is bridge created connecting eth2-eth5. If I make another VLAN I know the management interface must be connected to the new bridge and other ethernet ports. I’ve got another IP address that I’ll put on eth1 interface and I’m going to NAT it VLAN 11 with addresses 192.168.11.0. DHCP must be set for bridge interface on the new VLAN or I’m in mistake? Thank you.
