This script allows to use the free VPN service provided by VPNGate in an easy way. The user just needs to provide the desidered output country, and the script automatically chooses the best server.

After this step, OpenVPN is launched with the proper configuration. The VPN can be terminated by pressing Ctrl+C.

Usage

Run the script by providing the desired output country:

	# As the "bufferbloat" folks have recently re-discovered and/or more widely
	# publicized, congestion avoidance algorithms (such as those found in TCP) do
	# a great job of allowing network endpoints to negotiate transfer rates that
	# maximize a link's bandwidth usage without unduly penalizing any particular
	# stream. This allows bulk transfer streams to use the maximum available
	# bandwidth without affecting the latency of non-bulk (e.g. interactive)
	# streams.
