I want to provide both public and private (intranet) web service using pfSense for my firewall and DNS. Right now in pfSense under System / General Setup; my Domain is set to domainName.net, but I’ve purchased a public domain with NOIP with the same name but .com, already purchased a wildcard Cert and the Manage DNS came with a free single Cert and its already pointing to my local server and keeping it updated using Dynamic DNS.

I want to import both Certs to secure all connections both private and public using the Certificate Manager and by doing this using SSL on the HAProxy to direct all connections to the proper web server. So to make this setup work properly, the pfSense Domain name should be domainName.com correct?
