I’m currently running Let’s encrypt to remotely access services on my home server, and it’s working well. My setup is the following : for each service I have set up an A record ‘myapp1.domain.com’ which is accounted for by Let’s encrypt and whose IP is updated by my DDNS client and . So I have in total around 10 A records, each of them has a certificate by Let’s encrypt and each of them is updated by my DDNS client.
So my question comes down to : is it the most efficient setup ? (it certainly does not feel like it is)
Any insight much appreciated, thanks !
