Routing specific remote IPs through Site-To-Site

[dbennett]

I'm attempting to route 4 specific 172 addresses through a Site-to-Site OpenVPN tunnel.  I currently have the Server setup and have individual Windows 10 clients connected with very satisfactory response times.

So not to interrupt my developers while I'm deploying this into production (24/7 office), I've created another OpenVPN config and a different port on the server and have already created the OpenVPN Client on our local External pfSense.  Both the remote and local connections have been established.  From the Client firewall I'm able to ping one of my remote test destinations and can see the entries in the States table when I ping the 172 remote IP.

What do I need to do so that I can route that traffic through the OpenVPN?

Thanks ahead for your assistance.

This is old but the concepts should still apply.
