Problem with routing

[marcin70]

Hello everyone. i'm new in Kubuntu, but i have some experience in Linux.
After installation, routing on my wi-fi seems like this:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default _gateway 0.0.0.0 UG 0 0 0 wlp3s0
default _gateway 0.0.0.0 UG 600 0 0 wlp3s0
192.168.200.0 0.0.0.0 255.255.255.0 U 0 0 0 wlp3s0
192.168.200.0 0.0.0.0 255.255.255.0 U 600 0 0 wlp3s0
_gateway 0.0.0.0 255.255.255.255 UH 0 0 0 wlp3s0

I have openvpn connection, when I connect it seems like this:

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default _gateway 0.0.0.0 UG 0 0 0 wlp3s0
default _gateway 0.0.0.0 UG 1 0 0 wlp3s0

_gateway 0.0.0.0 255.255.255.255 UH 50 0 0 wlp3s0


After disconecting :

Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
default _gateway 0.0.0.0 UG 0 0 0 wlp3s0
default _gateway 0.0.0.0 UG 1 0 0 wlp3s0
dns.google _gateway 255.255.255.255 UGH 0 0 0 wlp3s0
kobra.tbtelecom _gateway 255.255.255.255 UGH 0 0 0 wlp3s0
192.168.200.0 0.0.0.0 255.255.255.0 U 0 0 0 wlp3s0
192.168.200.0 0.0.0.0 255.255.255.0 U 1 0 0 wlp3s0
_gateway 0.0.0.0 255.255.255.255 UH 0 0 0 wlp3s0


My problem is, I cannot connect with internet and computers in network behind openvpn and pptp connection..
In Windows clients everything works fine with openvpn and pptp connection.
It is my first experience with dynamic routing, and Linux with graphical GUI
I cannot resolve problem, have You any sugestion?

Ok, i think I solved problem.
When I tried app for openvpn, I install some app, who make mess in my routing table. I forget about it, and when I uninstall it, every thing work fine.

For information, it was openvpn gui, I not recommendet this app

edit:
Another tips, if after make You change in Your routing table, in log appears for example:


.... connmand[975]: wlp3s0 {del} route 0.0.0.0 gw 192.168.200.98 scope 0 <UNIVERSE>
.... connmand[975]: wlp3s0 {add} route 0.0.0.0 gw 192.168.200.98 scope 0 <UNIVERSE>

and it ruins Your routing table, in:

/etc/connman/main.conf

add:

[General]
EnableOnlineCheck=false
NetworkInterfaceBlacklist=<Your interface - eg. wlp3s0.>

edit2:
Here we go again. To this time I installed and maintained servers with Debian, with command line, where everything was easy, when I write something in config file, it was permanent and unchangeable. In Kubuntu many processes works in automagic way, and give to me new experience with every restart of the system, new changes, new symptoms, new problems



Sorry for my english, is not perfect and I make sometimes some mistakes
