Apache redirect all traffic to HTTPs except for private IP

Question

I would like to redirect all incoming traffic to HTTPs except for incoming traffic on private IP (10...*). With the following configuration, external traffic is not being redirected to HTTPs.

This VirtualHost for private IP

<VirtualHost 10.191.120.232:80>
    ServerName webservice.local
    ...
</VirtualHost>

Default VirtualHost to redirect all traffic to HTTPs

<VirtualHost _default_:80>
    ServerAdmin webmaster@localhost

    RewriteEngine On

    RewriteCond %{HTTPS} off
    RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI}
</VirtualHost>
