I have dropped debian-de...@lists.debian.org.
I have added debian-user@lists.debian.org.
In previous emails, Maximilian complaned that Debian 9 had no 'route'
command. Having been advised to use 'ip route', he has offered this
snippet from this interfaces file for discussion.

Maximilian, why are you using 'route' in those post-up and pre-down
directives?
If you're going to use post-up and pre-down, then they need to be more
like (untested) the following, using 'ip route':
post-up ip route add A.B.C.D dev ens18
post-up ip route add default via A.B.C.D
pre-down ip route del default via A.B.C.D
pre-down ip route del A.B.C.D dev ens18
More importantly, why are you using post-up and pre-down directives to
add default routing? Is there a reason why your netmask is
255.255.255.255?
Assuming that you're on a /24 subnet (meaning, the netmask is
255.255.255.0), then try something like this, instead:
auto ens18
iface ens18 inet static
address IP.V4.ADDR.ESS
netmask 255.255.255.0
gateway ROOTER.IPV4.ADDR.ESS
