      What CP is set for 59 minutes?  In these matters specifics count.

      DO NOT set a source address/port in a port forward or firewall rule unless you KNOW you need it!

        And FWIW I didn't hassle trying to get the DHCP status running on pfSense - screw with your router as little as possible.  I got it running on my Mac and scp'd the leases file over and ran it there occasionally until I was confident I had things right.  If you don't have a Unix host to run things like this, install Linux, FreeBSD, or even pfSense on something else and install stuff on that.

            Those happen.  They appear harmless.

            There is no use having an idle timeout of 59 with a hard timeout of 59.  Are you sure your idle timeout of 59 isn't good enough?  That means a user who is gone from your network for 59 minutes is logged out.

            What are your goals for your captive portal?

              Well I think my answer to this question will help "me" :)

              I want user to login CP (with provided user/password), after 59 min user should disconnected. Also to release/free IP address which he took.
              So maybe he will not re login after disconnect (59).

              Thanks for help.

                The hard timeout will do that.

                Also to release/free IP address which he took.

                Captive portal happens after a DHCP lease has happened.  Every device can get and keep a DHCP lease whether or not they even try to get on the internet or even look at the captive portal.

                So maybe he will not re login after disconnect (59).

                That is a function of whatever authentication backend you're using for captive portal.  Not DHCP.

                This is all assuming open, not WPA, Wi-Fi.
