no remote access to instance over VLAN

I have a Nova setup with which when I spin up an instance I can't ping or log into the instance off node through a VLAN. The switch has tagged VLANs set up, and I can create and use VLANs from one physical node to another and communicate through them. I've created and setup the network '172.17.87.0/24 1 256'. I've done the modifications in the database to the networks and fixed_ips tables, IPs 172.17.87.1 thru 172.17.87.7 are reserved, 172.17.87.7 is the gateway. I've changed the 'vlan' to 6 and the bridge to br_6.

My nova.conf file is: --dhcpbridge_flagfile=/etc/nova/nova.conf --dhcpbridge=/usr/bin/nova-dhcpbridge --logdir=/var/log/nova --lock_path=/var/lock/nova --state_path=/var/lib/nova --verbose --use_deprecated_auth --vlan_interface=eth3 --public_interface=eth3 --s3_host=172.17.86.7 --rabbit_host=172.17.86.7 --ec2_api=172.17.86.7 --ec2_url=http://172.17.86.7:8773/services/Cloud --routing_source_ip=172.17.86.7 --fixed_range=172.17.87.0/24 --network_size=1 --sql_connection=mysql://root:nova@172.17.86.7/nova

Solve it! I had to get rid of the br100 bridge, and use the straight eth3 interface.
