      I'm running a pfsense 2.2.4 installation without any problems for some time.
      Yesterday out of sudden a strange behaviour occured:
      First my personal android phone was always redirected to the portal page (of course, it is in the MAC pass through list) restarting the captive portal and even restarting the entire pfsense did not work.
      Today, my phone was again able to pass through without any problems, now some other phones and machine here in the office were not able to pass through (all on pass through list), while others still seem fine. Since a couple of minutes, my phone ist again not bale to pass through. My boss for example has two iphones (yes, two) one is still working, the other is also keeping redirected to the portal. Happens on different systems, windows, OSX, android etc.

      Any idea on this?

        If it is on the list, it will 'fall though' and the Portal login page will never show.

        So, be ready for some digging.
        Use THE tool : https://doc.pfsense.org/index.php/Captive_Portal_Troubleshooting

        List table 1,2,3 and 4. Two of these contain all the MAC addresses that can pass through.
        Your Phone is on the list ?

        I guess, when the portal page pop up on your phone, the MAC isn't present in the (2) tables anymore.

        What are you using to bridge between pfSense (the NIC) and your wifi devices ?
        An AP ?
        Is it in bridge mode (NOT router mode) ?
        All devices have good IP's listed on the DHCP server on pfSense ?

        No "help me" PM's please. Use the forum, the community will thank you.
        Edit : and where are the logs ??
