First, when you add member interfaces to a bridge, you should move all their
IP addresses to the bridge. That is, bridge member interfaces should
have no IP addresses, only bridge itself.

Second, you should re-read bridge(4) manual page and use
sysctl net.link.bridge.inherit_mac=1 and use physical NIC as first
bridge member so that your uplink has no reasons to filter
traffic of the bridge due to its fabricated MAC.
