I installed 7.450 on our ASG425 today and couldn't get ETH0 to link with my Cisco switch. Turns out that the ports are not being identified correctly. Port 0 is actually labeled as Port 4 on the appliance. I believe it's enumerating the ports beginning with the PCIe adapters, then PCI. If I remember, this was an issue that was solved in a previous release, but it's back with this new beta. This may also be a bug on other Astaro Appliances, but I can only test on a 425 right now.
This is not a bug. When you install an appliance ISO (not available as a beta), the nic order is correct. We have to sort them based on the appliance type, so this can't work for the software ISO.
