Since these two interfaces are attached to the same network segment,
only one of them belongs in the "INTERFACESv4" specification.
The one to keep is "br0", since that's the one for which you have
specified an IPv4 subnet.

I wonder whether you need "bridge_stp on". If you have just one
physical uplink ("enp5s0") and you don't have any loops in the
"inside" network, topology management with STP is superfluous.

I hope this helps.
