Comment 3 for bug 364101

I am having the same issue. I occasionally use very simple openvpn tunnels across already encrypted links and in those specific cases I'd like to have encryption off and no authentication. Here is an example config file:

------ cut here ----
remote 192.168.0.101 1000
dev tun0
ifconfig 10.10.10.2 10.10.10.1
proto udp
ping 5
link-mtu 1366
up-delay
daemon
---- end of config file ----

There is no way to implement this presently in "network-manager-openvpn". I'd suggest something like this:

1. Allow an "expert option" to simply specify an openvpn config file to be used for the connection.

2. Include an "advanced" area where the user is allowed to edit the options that will be used (e.g. what follows '/usr/sbin/openvpn' while referencing variable from the rest of the configuration gui. For example:

Edit Command Line: --remote $Gateway $lzo --nobind --dev $tun_or_tap --proto $proto --port $port ...etc

The gui would dynamically build this command line while you edited and/or checked/unchecked options (similar to the way several IDEs do for a compiler/linker).
