NethServer Version: 7.4
Module: Let Encrypt

The title of the topic say it all. How can I get a certificate for www.aaaaaaaa.nl and www.bbbbbbb.nl and mail.aaaaaaaa.nl and ftp.bbbbbbbb.nl… etc.

I want to set this as default.

thanks in advance, Pit

In dashboard go to:

“Server Certificate” -> In dropdown “Upload certificate” select “Request Let’s Encrypt certificate” -> in “Domains” write down your domains (one for line) -> click on “Request Let’s Encrypt certificate”

If it’s all ok you will return to “Server Certificate” -> click on dropdown “Show” near “Let’s Encrypt Authority X3” and select “Set as default”

Remember that ports 80 and 443 must be accessible from Internet.

Is “mydomain.at” resolvable via a public DNS and are ports 80 and 443 open at the server the domain resolves to.

Cheers.

OK, that can’t work… mydomain.at is pointing to my providers server, just for my homepage. I use mydomain.at even for my vm’s.

I have a dynamic IP at home were my vm’s are hosted. I use dyndns with no-ip for my vpn. I think I can’t use mx records then ?

In your mydomain.at DNS panel create, for every host that you want to point to your server, a CNAME that points to your no-ip hostname. Then create the MX records you need that point to your CNAME records.

In nethserver Insert these hosts in “DNS” - > tab “server alias”

OK, thank you for this information. I think I found another possibility. I have been able to configure mx-records on the no-ip portal, let me try that first…
