I’ve just installed certificates using the instructions bor Ubuntu and everything works great.
However, I needed some help with my particular setup where I’ve got multiple servers behind a firewall.
Here’s a simple network diagram that best explains what I have
[Router Port Forwarding]
- Server 1 [Port 80/443] Apache CertBot installed
- Server 2 [Port 8080/8443] Email Server
I suspect this might be common question that people have, but I have certbot installed and setup on server 1, and everything works fine and is secure.
However, server 2 doesn’t have proper security settings and is also running a email Webserver and doesn’t show up as secure.
So my question is: what do need to do to make sure that even server 2 shows the correct security certificates (from server 1)?
Server 2 is a legacy system and I cannot make changes to it.
