Units should always be generated the same way and I doubt restarting 
regenerates them.

Things you could try:

 - move the pre-up script to a separate unit that ifupdown depends on 
   (After= + Wants= or even Requires=)

 - switch to systemd-networkd

See also the description of network-online.target in systemd.special(7) 
and the linked document "Running Services After the Network is up".

Kind regards,
Andrei
