      Captive portal? They are going to have to punch through that before anything will work.

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

        Captive portal => a 'default' 2.6.0, installed from the USB/ISO will break things.
        When 2.6.0 came out, only TCP ( !! ) worked over the interface that has been set up with a captive portal.
        No UDP, no ICMP.

        You have to install the System patches pfSense package.
        In contains several 'must have' patches, one of the corrects the ipfw portal firewall handling.

        Btw : ones the portal user is connected to the portal, all ports, all protocols can be sued.
        No need to NAT or do what so ever.
        You'll be needing a GUI firewall rule like this :

        85ef1d89-6746-42a6-8b6e-0dff28259dc2-image.png

        on the captive portal interface of course.

        Edit : and where are the logs ??

          Hello I hope this link can help you, it did for me. I spliced all these connections with the Proxy.

          Ref:
          https://support.google.com/work/android/answer/10513641?hl=en

          If your using an Android Smartphone you need the following ports open

          TCP/UDP 5228-5230
          TCP 5235,5235

          Screenshot 2023-06-16 at 12.10.54 AM.png
          (also ref website above you need to allow traffic to the the destination hosts also if you are using a proxy)

          Androids would not work on my network until I approved those ports and hosts

          Just some of the regex expressions I used for this in my splice file.

          play.google.com
          android.com
          ^((alt[0-9]-mtalk.)|(mtalk.)|(mtalk-(staging|dev).))google.com
          google-analytics.com
          googleusercontent.com
          gstatic.com
          ^((gvt)([0-9])).com
          ggpht.com
          dl.google.com
          dl-ssl.google.com
          android.clients.google.com
          ^(((clients)[0-9])|accounts).google.(com|us)
          connectivitycheck.android.com

            Hi,

            Thanks Gertjan for your answer

            Thank you I had already installed the "System_Patches" package but I just updated it.

            I've also enabled logging on wifi call rules and I'm seeing traffic going through.

            fe538d0c-8805-4b35-a187-0e1e33df4bbb-image.png

            But I don't see anything on port 4500 and on the phone, wifi calls are still not active...

              I have authorized frames on the firewall for port 500 and 5228 but wifi calls are not active on the phone (I don't have the icon at the top right). What I find strange is that I never have a trace for port 4500...
              Is a NAT rule missing?

                No NAT needed. No special tricks needed. Why do you think you need to NAT something ?
                Just one firewall rule on the captive portal firewall rule page, the the firewall rule I've showed you above.

                I'm using the portal also, and when I connect my phone, I can do whatever I want. Visit whatever I want. All ports are open (for outgoing connections).

                True : I use 23.05.
                But back then, when I was using 2.6.0 - with the patch, the portal worked well.

                Show your captive portal firewall rules.
                Undo everything else.

                If you have Youtube, go here : Youtube Netgate.

                Look at every Captive portal video you can find (there are 3 of them).
                They are rather old, but still very valid.

                  I tested with the rule that allows everything.

                  However, wifi calls do not work. I don't have the icon at the top right of my phone...

                  I don't know where to look anymore.

                  something to configure in the System > Advanced > Firewall & NAT tab?

                    Noop. Pas besoin de changer quoi que ce soit la-bas.

                    The phone you use, did you connect to the portal ? You saw the login page ?
                    When authenticated, do you see this on the pfSense dashboard :

                    e94883ff-bb78-477d-9529-ca0ff81262c6-image.png

                    Do you have a phone ? Connect it. Install some network testing apps. Test DNS, as this uses normally UDP (can use TCP). It should work.
                    I'm not sure how to test UDP access.
                    When I take my iPhone, and connect to the portal, I can 'call' using whatever.
                    That is, dono what Wifi calling is actually. Why would I need that ?
                    Our/my ISP is Orange France (fibre).

                    If your far from "47500", drop by, I'll show you ;)

                    Calling using Whatsapp, telegram and I don't know what : works fine.
                    I can get called also.

                      I'm actually using a captive portal.

                      However, I added my phone as authorization by mac address.

                      On other forum topics, I find that there may be a DNS forwarding issue.

                      Also I use DNS Resolver for blocking Domain Overrides.

                      How to set up DNS port forwarding on NAT?

                        However,

                        When setting up things, keep everything simple - as basic as possible
                        No MAC adding. No IP allow, nothing.
                        Connect your device, check that you see the login page. Login with valid credentials.
                        Check the pfSense GUI that you are logged in.
                        Can you visit, for example google.com ?
                        Can you visit ... www.tf1.fr (tf1.fr wasn't in your local D?NS cache, this test validates DNS lookups).

                        How to set up DNS port forwarding on NAT?

                        You mean this : Redirecting Client DNS Requests ?
                        Such a redirect is optional.
                        True, there are people that 'insist' in using their DNS, not the DNS the device got by DHCP.
                        That's actually their choice.
                        A side effect is : they can't use the free (portal !!) wifi access at mac Donald's, neither Air France, neither SNCF. And yes, neither your wifi portal. It's their choice ;) Their choice can't be your issue.

                        But, yes, I admit, I also feel bad for those people.
                        So I actually did what was explained on that "Redirecting Client DNS Requests" :

                        8a2ef651-3ff9-4d9b-85b1-c277e00c97e2-image.png

                        but again : this is not needed to make things work.
                        It's just an anti-shoot-in-the-foot measure.

                        These are the first 3 rules of my captive portal :

                        ed23bcd1-9627-4445-afb9-efa69794f980-image.png

                        The first one is the firewall rule that was added by the NAT rule.
                        As you can see, the counter in front of the rules are not zero : so this firewall rule (and redirecting) has been activated for some portal visitors.
                        Most (low bud !) phones - or their even more stupid (sorry) owners insist on using their own DNS IP : they got redirected to ..... pfSense 127.0.0.1 so the resolver can do it's work for them. If this wasn't they case, DNS would not work for them (as initially the portal doesn't allow any external access !!).
                        Happily enough : this is a small minority.

                        The second rule authorizes express all DNS traffic to the pfSense Portal interface : these counters are way higher : which shows most devices to play by the rules : they use the DNS that pfSense DHCP has been given to them 👍

                        The third rule : This is a safe barrier. If I missed something then let them (the portal visitor) take the wall. This rule is never used, so I took care of all the port 53 TCP/UDP traffic.

                        Also I use DNS Resolver for blocking Domain Overrides.

                        Just for my own curiosity :
                        First : you add domain overrides.
                        Then : you have to block them ?

                        I have a domain override :

                        4cffca0d-f7e0-4dd1-9ac8-f4b475be26e0-image.png

                        Where 192.168.2.1 is my pfSense portal IP network.
                        I need to have a host name, as I'm using https portal login page. Http is pretty dead these days, and most browser just don't allow it anymore, or start to yell 'security issue ahead' !
                        Portal visitors will panic and say to you : "problem" ?!
                        https usage is optional, of course.
