# 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.

# 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:

#   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.

# or bridge the TUN/TAP interface to the internet
# in order for this to work properly).
