  109. # EXAMPLE: Suppose the client
  110. # having the certificate common name "Thelonious"
  111. # also has a small subnet behind his connecting
  112. # machine, such as 192.168.40.128/255.255.255.248.

  116. # Then create a file ccd/Thelonious with this line:
  117. # iroute 192.168.40.128 255.255.255.248
  118. # This will allow Thelonious' private subnet to
  119. # access the VPN. This example will only work
  120. # if you are routing, not bridging, i.e. you are
  121. # using "dev tun" and "server" directives.
  122. # EXAMPLE: Suppose you want to give
  123. # Thelonious a fixed VPN IP address of 10.9.0.1.
  124. # First uncomment out these lines:
  125. # option client_config_dir /etc/openvpn/ccd

  127. # list route "192.168.100.0 255.255.255.0"
  128. # Then add this line to ccd/Thelonious:
  129. # ifconfig-push "10.9.0.1 10.9.0.2"
  130. # Suppose that you want to enable different
  131. # firewall access policies for different groups
  132. # of clients. There are two methods:
  133. # (1) Run multiple OpenVPN daemons, one for each
  134. # group, and firewall the TUN/TAP interface
  135. # for each group/daemon appropriately.
  136. # (2) (Advanced) Create a script to dynamically
  137. # modify the firewall in response to access
  138. # from different clients. See man
  139. # page for more info on learn-address script.
  140. # option learn_address /etc/openvpn/script
  141. # If enabled, this directive will configure
  142. # all clients to redirect their default
  143. # network gateway through the VPN, causing
  144. # all IP traffic such as web browsing and
  145. # and DNS lookups to go through the VPN
  146. # (The OpenVPN server machine may need to NAT
  147. # the TUN/TAP interface to the internet in
  148. # order for this to work properly).
  149. # CAVEAT: May break client's network config if
  150. # client's local DHCP server packets get routed
  151. # through the tunnel. Solution: make sure

  153. # a more specific route than the default route
  154. # of 0.0.0.0/0.0.0.0.
