If it appears that OpenVPN will not push routes to a client, ensure that a
Multi-site style PKI/SSL setup is in use
and not a shared key setup or an
SSL/TLS setup using a /30 tunnel network.
Routes cannot be pushed on a shared key setup or an SSL/TLS setup using a /30
tunnel network. Routes may be directly added to the client configuration using
the IPv4 Remote Networks list (e.g. 192.168.99.0/24, 192.168.203.0/24)
