      Hello

      I would like to report something

      I use pfsense 2.1 as intervlan routing to my campus
      All LAN clients in VLANS are able to be pinged from WAN
      Intervlan function seem to be working fine.

      campus
      10.0.0.0/8
            |
            |
      10.44.1.254/24
      pfsense
            |
        (trunk)
            |
      Layer 2
      Switch
            |
      VLANS
      10.44.x.x/24

      Then, I activated the captive portal to auth access to our hotspot VLANs ( we have 5 VLANs, one for each floor)
      To provide ROAMING function , I use passthrough MAC function Auto entry, so when new user logged-in to one hotspot VLANs, his/her MAC are stored in passthrough MAC table, along with his/her username.

      After users started to logged in, within minutes, lots of MACs are stored to the table
      By this time, I started to see pattern of CPU spike every 60 minutes.

      What do you guys think this is? Is this normal for Captive Portal with 300+ MACs in the passthrough table?
      Thanks for all reply.

        I think I found a solution from this thread

        https://forum.pfsense.org/index.php?topic=51468.0

        I did 2 changes:

        1. Change WAN IPV6 Configuration, from DHCP to NONE
        2. Advanced - Networking - IPV6, uncheck Allowed IPV6

        Problem solved. I hope it will help other people.
        Thanks
