I just went through this write up and everything went smooth when I read all of the notes about the ACLs. The only outstanding question that I have is the use of bridges mentioned here. When I was building the container I saw the option to use MACVLAN so I choose that and everything seems to be fine. The container has it’s own IP address and transfer rates seem to be very good.
Any reason not to use MACVLAN?
Bridge makes things easier if you do things like change an interface and I think (unless this has changed recently) that if you don’t use a bride the container can’t talk to the TrueNAS IP.
You are correct. I have been doing a little more reading and MACVLAN will not allow communication between the container and the host. But the devices that will be using this backup server are not on my TrueNAS server so that is not an issue. I have also ready that there is better performance with a MACLAN because the traffic does not pass through a software switch. I have not tested that.
