I got a .ovpn file from our "network guy".
I tried to import it to NetworkManager, but that didn't work:

 $ sudo nmcli connection import type openvpn file ~/.ssh/foo.ovpn

The connection appeared in the UI, but can't connect.

So I tried connecting on a command line:

sudo openvpn --config ~ondra/.ssh/arpage/ozizka@kufw1-1.arpage.ch.ovpn

This works. Although, all traffic goes through that VPN. The only thing that resembles the option "Only use this connection for it's traffic" in NetworkManager's UI is route remote_host, but openvpn complains about it, so I had to comment it out.

  • How can I change the routing in the .ovpn file?
  • Where is the reference manual for the .ovpn file?

Here's a part of that file:

dev tun
proto tcp
remote *** 20443
verify-x509-name "..."
#route remote_host net_gateway
resolv-retry infinite
cipher AES-256-CBC
auth SHA256
comp-lzo no
route-delay 4
verb 3
reneg-sec 0

Not sure if remote_host has some special meaning or is an alias for The issue at my side was that there was pseudo-default route pushed from the OpenVPN server: routed to vpn_gateway, and that was somehow killing the traffic.

So originally I did

sudo route del -net netmask
# Or - equivalently:
sudo ip route del

And later, the "network guy" removed it from the commands pushed by the OpenVPN server.
