+# 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.
+# First, uncomment out these lines:
+;client-config-dir ccd
+;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:
+;client-config-dir ccd
+;route 10.9.0.0 255.255.255.252
+# 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
