Screenshot showing the not-working-setup

When adding a static route with the "Verbindungs-Editor" in KDE, the network manager can't connect to the network anymore.

Adding a route manually with `route` works as expected. e.g. `sudo route add 10.196.0.194 gw 192.168.0.100 eth0`

I have pretty much default network from a cable provider. My computer has the static IPv4 address 192.168.0.5. The default gateway is 192.168.0.1 Network-Mask: 255.255.255.0 this works so far. I have a second router with IP 192.168.0.100 where a device with IP 10.196.0.194 is connected. Thus I used to add a static route for this address using 192.168.0.100 as Gateway.

Before Kubuntu 16.04 I had added a route with plasma-nm and it worked properly. Since 16.04 I can add the route with plasma-nm, but when doing so the network is not connecting anymore.

Comment 1 georg 2016-06-08 11:28:00 UTC 
By the way: translating programm-names in different languages is really not a good idea. Another thing: it's really hard to figure out whats the programms name, causing the problem. It's almost impossible to translate the german programm name "Verbindungs Editor" into "plasma-nm". THis should at least stand in the "About" Section of every programm....
Comment 2 Jan Grulich 2016-06-08 11:59:39 UTC 
Could you please provide log from NetworkManager once you try to connect to the modified connection? Or is there any notification with error?
Comment 3 georg 2016-06-08 12:22:56 UTC 
`/var/log/syslog/` shows this when adding the route, which looks fine:

By the way, the following error message also appears, when no route is entered. (The network works flawlessly then anyway):

------------
Jun 08 14:26:48 xxx nm-dispatcher[12169]: req:1 'up' [eth0], "/etc/NetworkManager/dispatcher.d/01ifupdown": complete: failed with Script '/etc/NetworkManager/dispatcher.d/01ifupdown' exited with error status 1.

------------

I think the problem might be with messages from `org.kde.kdeconnect`
Comment 5 Jan Grulich 2016-06-13 10:12:03 UTC 
Could you please verify whether all your IPv4 addresses/routes are correct when you run "nmcli connection show your_connection_name"? If they are correct, then it means that we (from plasma-nm) set it correctly and there is a problem in NetworkManager and not in plasma-nm.
Comment 6 georg 2016-06-14 08:25:15 UTC 
Here the relevant output of the command `nmcli connection show Kabel` where "Kabel is the name of my connection:

----------------------
ipv4.addresses:                         192.168.0.11/24
ipv4.gateway:                           192.168.0.1
ipv4.routes:                            { ip = 10.196.0.194/8, nh = 192.168.0.100 }
----------------------

This helped me to figure a working resolution:
When I change the Route to one of the following pairs it works:
* IP: 10.0.0.0, SubnetMask: 255.0.0.0
* IP: 10.196.0.194, SubnetMask: 255.255.255.255

With one of this configuration the `nmcli`-command gives me:
----------------------
ipv4.addresses:                         192.168.0.11/24
ipv4.gateway:                           192.168.0.1
ipv4.routes:                            { ip = 10.0.0.0/8, nh = 192.168.0.100 }
----------------------
OR
----------------------
ipv4.addresses:                         192.168.0.11/24
ipv4.gateway:                           192.168.0.1
ipv4.routes:                            { ip = 10.196.0.194/32, nh = 192.168.0.100 }
----------------------


However, before the upgrade it also worked with the pair [IP: 10.196.0.194, SubnetMask: 255.0.0.0].
It's upon you to leave it, or fix it, since this was clearly a misconfiguration. (A error/warning message would be nice though ;-)

THanks for your help!
Comment 7 Jan Grulich 2016-06-14 12:04:48 UTC 
I cannot fix this in plasma-nm, you would need to report this problem to NetworkManager.
