I am not sure either but the working setup also has the IP address on =
the physical interface.

As a test, I created a bridge and added the igb0(4) interface (which =
connects to the pppoe modem). The mac addresses from that LAN (i.e. the =
modem's and a second server's) are learned by the bridge!  So the bridge =
learns addresses from igb0 but not from igb1!  The igb0/1 are two ports =
on an Intel 82576:

igb0: <Intel(R) PRO/1000 Network Connection version - 2.4.0> port =
0xdc00-0xdc1f mem =
0xdf6e0000-0xdf6fffff,0xdf6c0000-0xdf6dffff,0xdf69c000-0xdf69ffff irq 16 =
at device 0.0 on pci6
igb0: Using MSIX interrupts with 9 vectors
igb0: Ethernet address: c8:0a:a9:c8:7e:86
igb0: Bound queue 0 to cpu 0
igb0: Bound queue 1 to cpu 1
igb0: Bound queue 2 to cpu 2
igb0: Bound queue 3 to cpu 3
igb0: Bound queue 4 to cpu 4
igb0: Bound queue 5 to cpu 5
igb0: Bound queue 6 to cpu 6
igb0: Bound queue 7 to cpu 7
igb1: <Intel(R) PRO/1000 Network Connection version - 2.4.0> port =
0xd880-0xd89f mem =
0xdf620000-0xdf63ffff,0xdf600000-0xdf61ffff,0xdf5dc000-0xdf5dffff irq 17 =
at device 0.1 on pci6
igb1: Using MSIX interrupts with 9 vectors
igb1: Ethernet address: c8:0a:a9:c8:7e:87
igb1: Bound queue 0 to cpu 8
igb1: Bound queue 1 to cpu 9
igb1: Bound queue 2 to cpu 10
igb1: Bound queue 3 to cpu 11
igb1: Bound queue 4 to cpu 12
igb1: Bound queue 5 to cpu 13
igb1: Bound queue 6 to cpu 14
igb1: Bound queue 7 to cpu 15

I won't be able to physically swap the two ports until later this week =
but now I think this might be a bug somewhere rather than a config =
issue.
