OpenVPN giving a client a static IP

To set up static IP for a client first set up client-config’s in server.conf

# 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 client-configs

Then create the directory “/etc/openvpn/client-configs
Then create a file with the name of the client that is connecting in this folder
(for instance “/etc/openvpn/client-configs/backup”)

#Give this machine 10.8.0.3 a a static ip
ifconfig-push 10.8.0.3 10.8.0.0

(Remember to replace with values that makes sense to you)
