Hi Pavel,
Thanks for your update. I also saw that the post are both online but I
thought the second nic only advertises the mac so the switch does not
get confused.
The issue might be that i do VRRP, so the bond is connected to two
switches, they are not stacked, only trunked as that's what VRRP
requires and works well on the side where there is only one VLAN on
the Host interface.
It just goes wrong on multiple vlans.
This is what I see everywhere.
Mode 1 (active-backup)
This mode places one of the interfaces into a backup state and will
only make it active if the link is lost by the active interface. Only
one slave in the bond is active at an instance of time. A different
slave becomes active only when the active slave fails. This mode
provides fault tolerance.
It's sure I need to get my traffic back on my sending port, so that is
why the arp for the passive port was there I thought.
Are there other modes that should be working on VRRP in your understanding ?
Thanks a lot,
Matt

In mode=1 the active interface sends traffic, but both interfaces
accept incoming traffic. Hardware switches send broadcast/multicast/unknown destination
MACs to all ports, including the passive interface. So packet sent from the active
interface can be received back from the passive interface. FreeBSD CARP just would go mad
when it receives its own packets.
I believe if you get Linux implementation, it will work well in the same network setup. I
use keepalived in oVirt VMs with bonded network, and have no issues.

How can it lead into packet duplication when the passive should not be
active and only it's mac-address should be visible on the switch to
prevent confusion on the switch ?
For a VRRP setup on the switch there is no other option then mode=1 as
far as I know ?

> I would say that bonding breaks CARP somehow. In example mode=1 can lead to packet
duplication, so pfsense can receive it's own packets. Try firewall in pfsense all
incomming packets that have the same source MAC address as pfsense.
