Save the route script to /usr/local/lib/openvpn/route on the client. Make it executable with chmod +x.

Remove the push redirect-gateway option from the OpenVPN server config.

Add these options to the OpenVPN client config:

setenv OPENVPN_ROUTE_TABLE 94
route-noexec
route-up /usr/local/lib/openvpn/route
route 0.0.0.0 128.0.0.0

/* 
 * Adds name constraints to a certificate.  Useful if you need to
 * import your organization's private CA into your web browser, but
 * you only want to trust it for your organization's domains and not
 * the Internet at large.
 *
 * The certificate is re-signed by an ephemeral issuer with a random
 * key so you don't need access to the private key.  A random serial number
 * is placed in the Issuer DN so browsers don't attempt to verify the
 * signature when you import the certificate.
