Acme and captive portal
-
Hi all.
I have configured a captive portal in fpsense 2.5.2 that is working correctly. When you connect to Wi-Fi, the browser opens and asks for a username and password. The problem is that the browser has to be firefox because it is the only one that accepts the certificate that comes by default in pfsense.
From what someone told me on these forums some time ago and I don't remember his name, I need to install acme to automatically renew the certificates. I have many doubts when it comes to configuring it, since my machine only acts as a firewall between my internet provider and my local network, therefore I do not have any dns (in dns resolve I configure it to resolve another dns from my provider to go to the internet ) and in dns host Overrides I set the captive portal as portal.mydomain.local. When you connect to it, portal.mydomain.local:8003 appears as the authentication page.
All the documentation I have seen refers to having dns services.
When creating the keys there are two types staging and production. I guess I'll have to use production.
In the section of creating the certificate in "DOMAIN SAN LIST" I don't know what options to take
If someone can guide me I would appreciate it. Thank you.
