# Sample client-side OpenVPN 2.0 config file #

# This configuration can be used by multiple #
# clients, however each client should have #
# its own cert and key files. #
# #
# On Windows, you might want to rename this #
# file so it has a .ovpn extension #

# will be pulling certain config file directives
