Probably I go thought a Ubiquity Dream Machine Pro.....
Ubiquity's stuff doesn't just magically setup a bunch of subnets or VLANs. Did you configure those or not?
On that same settings page is a Local Networks option.
Comma separated list of IP addresses or IP/netmask entries for networks that will be considered to be on the local network when enforcing bandwidth restrictions. If set, all other IP addresses will be considered to be on the external network and will be subject to external network bandwidth restrictions. If left blank, only the server's subnet is considered to be on the local network.
