That was very helpful. Setting mac_filter to off fixed the problem.
The documentation is now more clear. When mac_filter is turned on (the default), the container can only send packets with the MAC address that is assigned to the container. The container is not allowed to send packets with any other MAC address.
uCarp sends packets from a multicast MAC address by default, but those packets are not accepted by veth. You can have uCarp send from a broadcast MAC address, as well, but those packets are not accepted for the same reason. Setting mac_filter off allows the container to use whatever MAC address it wants.
Since this is a moderated forum, requiring 10 posts before allowing links seems more punitive than useful.
