OpenLDAP multi-master with a bunch of custom schemas.

Can you explain what you mean with lightweight?

You expressed yourself just fine and my question is still valid. Do you have the capacity to handle multi Tbit traffic on the edge ips that you use to hide the backend ips? Because if all of those are flooded, not only will the backend app be unreachable, but all your customers will be unreachable as well.

Even if you can get the appZTNA stuff to work (which I doubt), how is your infra going to absorb multi Tbit traffic without customer impact?

You will be in for a surprise once you learn about tcpdump ;-) Welcome to internet hosting!

Read the changelogs from 1.5.3 to 1.5.5 and see if you need to take additional steps

ngircd has the concept of a global password. Distribute this password and you’ve got a simple psk based acl mechanism

what error message are you getting?

It all depends on what you do with the box, how the applications you run utilize the cpu (single vs multithreaded/multiprocess but also stuff like cpu cache utilization. if you profile the workload that you want to run (see if its cpu, memory or io bound for instance) will help you in figuring out what works best for you.

Have a look at mailcow if you’re new to MTA’s. Use that and a (sub)domain to figure out how to set things up. Once youre satisfied with the setup, reconfigure your domain on the new MTA. Use a mailclient with $yourformat and imap support to import your old email.

And above all, dont be discouraged by the naysayers that think its an impossible task; Its not, but it is complicated to get right bc all the parts involved ;-)
