Captive portal with mac pass through and still with a first redirection

[rdubois]

Dear,

I would like to setup a captive portal with the following requirements:

1. The users needs to fill in a registration form for WiFi usage
2. Once he entered valid information, he will access internet and his MAC address will be used for MAC pass through (built-in pfsense feature)
3. The user is redirected to a portal page (and not to the original URL) - after authentication redirect

Question:
When the user comes back the second time (or after expiration of the hard timeout), step 1-2 should be ignored (the mac of the device is already known) but we would like to have the step 3 (first redirection) to a portal page (without authentication but only with a disclaimer and a submit button).
Is it possible to implement this ? How to proceed ?

Nope. Code is on github.
