I did some more research
I stopped Network Manager and started debug
# systemctl stop NetworkManager
# sudo /usr/sbin/NetworkManager --debug --log-level=DEBUG
I set the routes manually
$ nmcli con modify "uk-vpn" +ipv4.routes "10.100.100.189/32,10.100.100.190/32"
$ nmcli con show "uk-vpn" |grep ipv4.routes:%s/
ipv4.routes: { ip = 10.100.100.189/32 }; { ip =
10.100.100.190/32 }
When I changed the connection (VPN in my case), it seems that
As soon as I go to the GUIDE I can see both routes and the netmask
10.0.0.189 255.255.255.255
10.0.0.190 255.255.255.255
But as soon I modify, i.e. the netmask (let's say 255.255.255.254) and click
apply, all routes without gateway disappear
$ nmcli con show "uk-vpn" |grep ipv4.routes
ipv4.routes:
Yet in the logs it seem like all went good and successfully saved
$ apt show network-manager
