you need to have the routes configured properly, which depends on your environment.
Maybe should I ask on debian mailing-lists (not that much active, not sure I can get more relevant help than here)?
Well, NM should get it right automatically. If it doesn't, then you should look at the routes to understand what's wrong. What gives: ip route
Currently I’m not at the needed local network, so doing it at home, with normally configured network, I get:
galex-713@portable:~/doc/comp/src/pharo/opensmalltalk-vm$ ip route default dev tun0 proto static scope link metric 50 default via 192.168.1.254 dev enp0s25 proto static metric 100 89.234.186.64/27 dev tun0 proto kernel scope link src 89.234.186.82 metric 50 169.254.0.0/16 dev enp0s25 scope link metric 1000 192.168.1.0/24 dev enp0s25 proto kernel scope link src 192.168.1.38 metric 100
When enabling “VPN config > IPv4 Settings > Routes… > Use this connection only for resources on its network” checkbox, I get this:
galex-713@portable:~/doc/comp/src/pharo/opensmalltalk-vm$ ip route default via 192.168.1.254 dev enp0s25 proto static metric 100 89.234.186.64/27 dev tun0 proto kernel scope link src 89.234.186.82 metric 50 89.234.186.190 via 192.168.1.254 dev enp0s25 proto static metric 100 169.254.0.0/16 dev enp0s25 scope link metric 1000 192.168.1.0/24 dev enp0s25 proto kernel scope link src 192.168.1.38 metric 100 192.168.1.254 dev enp0s25 proto static scope link metric 100
I’m under Debian GNU/Linux stable, x86 (32bits).

both interfaces are only present, but only tun0 works in the first case, and only enps25 works in the second.
