I'm trying to figure out a way to get my networking.service to work properly, so networking service restarts work.
How do I setup those 20 IP'S with 2 different Gateways but only 1 NIC? With 2 NIC's I wouldn't have any problem, but is that possible on 1 NIC?
This is what I get when I try to restart it by using systemctl restart networking.service:

A explanation of the IPS:
45.XX.XX.XX are the first IP's from subnet 1 with Gateway 45.XX.XX.1
5.XX.XX.XX are the second IP's subnet 2 with Gateway 5.XX.XX.1
My /etc/network/interfaces looks like this:
source /etc/network/interfaces.d/*

And I have a /etc/iproute2/rt_tables which looks like this:
#
# reserved values
#
255 local
254 main
253 default
0 unspec
#
# local
#
#1 inr.ruhep
1 rt2
Thanks in advance!
