The /etc/network/interfaces is attached. Ignore the custom "multi-*" settings in there, they are used by an /etc/network/if-up.d script setting up firewalling. The VM is a VirtualBox (from Debian Unstable) with two virtual e1000 network interfaces, both connected to different host-only adapters. Could this related to my "ln -s /dev/null /etc/systemd/network/99-default.link" trying to get rid of that ugly enFOO interface renaming introduced in Stretch? Right now I am using the attached networking-hotplug.service / networking-hotplug-ifup.sh combo to work around it, practically extracted the --allow=hotplug part of the /etc/init.d/networking script. c'ya sven-haegar -- Three may keep a secret, if two of them are dead. - Ben F.
