| O.K., that should work. My best advice here is to do what I did - which is

Well, stopping the firewall a few seconds can't do really bad things, and,
well, pfctl -d, wait a bit, try again, still no luck...
The network is pretty simple,
gateway :
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=b<RXCSUM,TXCSUM,VLAN_MTU>
inet6 fe80::207:e9ff:fe0e:dead%em0 prefixlen 64 scopeid 0x1
inet6 2a01:678:1:443:: prefixlen 64
inet6 2a01:678:100:: prefixlen 48
first machine :
bridge0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
inet6 fe80::2d0:dead:beef:cafe%bridge0 prefixlen 64 scopeid 0x4
inet6 2a01:678:1:443::443 prefixlen 64
destination machine :
fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=8<VLAN_MTU>
inet6 fe80::2b0:d0ff:fee1:c05f%fxp0 prefixlen 64 scopeid 0x1
inet6 2a01:678:100:2:: prefixlen 48
All three ports on a switch.
I don't believe it's a problem in if_bridge(4) because it's the same if I try
from outside my network.
