--route-up cmd  : Run command cmd after routes are added.
--route-pre-down cmd : Run command cmd before routes are removed.
--route-noexec  : Don't add routes automatically.  Instead pass routes to
                  --route-up script using environmental variables.

                  by server EXCEPT for routes and dhcp options.
--allow-pull-fqdn : Allow client to pull DNS names from server for
                    --ifconfig, --route, and --route-gateway.
--redirect-gateway [flags]: Automatically execute routing
                  commands to redirect all outgoing IP traffic through the
                  VPN.  Add 'local' flag if both OpenVPN servers are directly
                  connected via a common subnet, such as with WiFi.
                  Add 'def1' flag to set default route using using 0.0.0.0/1
                  and 128.0.0.0/1 rather than 0.0.0.0/0.  Add 'bypass-dhcp'
                  flag to add a direct route to DHCP server, bypassing tunnel.
                  Add 'bypass-dns' flag to similarly bypass tunnel for DNS.
--redirect-private [flags]: Like --redirect-gateway, but omit actually changing
                  the default gateway.  Useful when pushing private subnets.

--shaper n      : Restrict output to peer to n bytes per second.
--keepalive n m : Helper option for setting timeouts in server mode.  Send
