Ok, looks all good.
DNS works - pfSense is the DNS resolver for your clients.

You use the default login page ?

What GUI firewall rules on your captive portal interface ?

fahad77678 · Jan 8, 2019, 5:43 AM

All is on default settings. Gui Login all is on default settings. Yoy can say that firewall is on default settings i had just configure captive portal

@fahad77678 said in Captive portal not redirecting on https requests. problem on every browser:

Its only works when i delete the browser history. Then when i entered the google.com and every dns with .com when i use the it redirects to login page. but when the session expire the its does not redirecting to me on login page. i want that if i entered only a single word in google it should redirect to me into login page if i am not logged in

Again : that is an expected behaviour.

It is not possible to redirect HTTPS connections. Not only with pfSense, but also with any other router. HTTPS connections just can't be redirected, that's by design. You can learn more here : https://stackoverflow.com/questions/51562003/captive-portal-and-https-redirect

That shoudn't be an issue because modern web browsers do handle captive portals pretty well, using HTTP test requests (cf my picture above)

fahad77678 · Jan 8, 2019, 7:15 AM

@free4
yeah i have checked your picture but its only works in firefox not on another browsers. how would it be possible on google chrome?

free4 · Jan 8, 2019, 7:23 AM

@fahad77678 chrome also implement captive portal tests

Android and apple devices also implement this feature

fahad77678 · Jan 8, 2019, 7:37 AM

@free4
But in my case chrome not doing like this.
can you come on teamviwer ?

fahad77678 · Jan 8, 2019, 7:55 AM

@free4
Did you enable https login enable in captive portal or not?
in my case if i disable https login then it cant reach the login page. chrome says site cant be reach if i search some sites.
same case in firefox. firefox only promt for login netwrok but not redirecting to catptive page.

The browser indicates that a user action is needed.
It's probably not directing you right away some where else, which seems rather logic to me: the user wants to browse site a.b.c. - the browser won't take him to d.e.f (our captive portal login page) but suggests the a user action is needed.

These are my observations :
Use http (default) and the https portal login. Things will go very smooth.
Chrome might be "portal aware" these days. I'm using the captive portal in a hotel - do not explain clients how to connect - and they connect (mostly not being IT experts, they all manage to connect using whatever device).

As said here - and in the doc : https you should obtain a certificate signed by an authority.
This implies that you should use an existing domain name on your portal LAN, like
portal.your-domaine.tld
You can buy such a corticate - or use the acme package.
True : the acme package works for you if you know what to do and how to do it

what do you mean by this how can i do this in pfsense. actually i m new in pfsesne

@gertjan

The Resolver : nothing to do. The default settings - as set on installation, are just perfect.

@gertjan
is it necessary to add captive portal ports add in firewall's wan and lan rules ?

Two cases :
If you activate the portal on the LAN you have nothing to do : the default firewall rule is a pass-all, the portal will work right away.
If you activate the captive portal on an extra interface (the best choice !), like OPT1, you have to, initially, add one firewall rule : the same one as you can find on the LAN interface.
Like this :

Never ever add firewall rules to the WAN interface. Rules for that interface belong to the experts.
