Codeigniter 4 on local server simultaneously for LAN and for internet

hello friends

Maybe this is a question for apache gurus, but I gently ask it here.

Given that I have a fixed public IP from my DSL provider and that if needed it could be taken a free DNS name for that public IP

I'm wondering if it is contemplated to have a local PC running an apache server that hosts a CodeIgniter 4 app that will be used simultaneously from remote and local clients

Well , in the case the answer is yes:

which is it the suggested setup?

During my development I create a virtual host in apache and set it up on my client/s the host file

but when it comes the time to share this local host ALSO for the outside world? e.g. what about site_url() ?

Thank you for any help
