Server behind Wireguard and Firewalld, Public IP and PTR
I am new to Digitalocean. I have mostly successfully set up a fedora droplet running wireguard and firewalld with a floating ip to direct traffic to a roaming laptop running a small web and mail server that reconnects automatically as it is moves to different locations. So far during testing on the backup laptop and test domain, it works great, the web server works great, IMAP works great, cal/carddav, perfect.
BUT I just ran into an issue with my project, I just now I realized that the PTR record uses the public IP and not the floating IP, which make email sending a problem. So I think I need to try using the public ip of the droplet instead of the floating ip at least for the email and maybe for all of my project to set up the PTR.
Looking for suggestions, Is there a guide or a different way to do this? And, for reasons I can’t get into now, I can’t migrate anything off the laptop server to a new proper server at the moment, but will eventually.
Thanks in advance.
