Home business SSL and public/private domain(s) setup

pfsense16v

Hello All,

I have a home-based business. I've been expanding my network capabilities but I've come across an area where I have little to no experience- certificates and private/public domains- and hoping I can get your advice on a starting point. Forgive me for my ignorance if I don't use the correct terminology.

My scenario:

I want to get SSL up and running on my pfSense firewall and my home NAS.
I have a public domain, mycompany.com. I have an internal domain, mycompany.lan.
I have a dynamic WAN IP.

Given this environment, what would be your recommendations on the first steps?

I've seen some discussions on the forum in using Let's Encrypt but I don't know if I could use that same cert on my firewall and NAS.

My company domain has a free SSL. Can I use that one on my internal LAN?

I've been procrastinating on this for a long while now and need to get it done once and for all.

Thanks in advance for any advice or recommendations you can provide.
