How to Allow your own domains through captive portal

how to Allow your own domains name through captive portal instead of an ip address

You are going to have to elaborate a bit more on what the goal is.

Thank you for that , well i want to have domain on captive portal when use connect trough my pfsense server , so that they can’t able to see the ip Address am using .
thank you

It has been a while since I have setup a captive portal, but you need to have a pre-authorized list of sites, including your domain for it to work.

can you help me to show me the way how to do it

I have not used them in years, I don’t usually recommend them due to the headache they create getting devices connected. Try the Netgate forums
