+
+	# To assign specific IP addresses to specific
+	# clients or if a connecting client has a private
+	# subnet behind it that should also have VPN access,
+	# use the subdirectory "ccd" for client-specific
+	# configuration files (see man page for more info).
+
+	# EXAMPLE: Suppose the client
+	# having the certificate common name "Thelonious"
+	# also has a small subnet behind his connecting
+	# machine, such as 192.168.40.128/255.255.255.248.

+#	option client_config_dir /etc/openvpn/ccd
+#	list route "192.168.40.128 255.255.255.248"
+	# Then create a file ccd/Thelonious with this line:
+	#   iroute 192.168.40.128 255.255.255.248
+	# This will allow Thelonious' private subnet to
+	# access the VPN.  This example will only work
+	# if you are routing, not bridging, i.e. you are
+	# using "dev tun" and "server" directives.
+
+	# EXAMPLE: Suppose you want to give
+	# Thelonious a fixed VPN IP address of 10.9.0.1.
+	# First uncomment out these lines:
+#	option client_config_dir /etc/openvpn/ccd
+#	list route "10.9.0.0 255.255.255.252"
+#	list route "192.168.100.0 255.255.255.0"
+	# Then add this line to ccd/Thelonious:
+	#   ifconfig-push "10.9.0.1 10.9.0.2"
+
+	# Suppose that you want to enable different
+	# firewall access policies for different groups
+	# of clients.  There are two methods:
+	# (1) Run multiple OpenVPN daemons, one for each
+	#     group, and firewall the TUN/TAP interface
+	#     for each group/daemon appropriately.
+	# (2) (Advanced) Create a script to dynamically
+	#     modify the firewall in response to access
+	#     from different clients.  See man
+	#     page for more info on learn-address script.
+#	option learn_address /etc/openvpn/script
+
+	# If enabled, this directive will configure
+	# all clients to redirect their default
+	# network gateway through the VPN, causing

+	# and DNS lookups to go through the VPN
+	# (The OpenVPN server machine may need to NAT
+	# the TUN/TAP interface to the internet in
+	# order for this to work properly).
+	# CAVEAT: May break client's network config if
+	# client's local DHCP server packets get routed
+	# through the tunnel.  Solution: make sure
