      I have found a problem after upgrading from 2.1-BETA0  Built On: Wed May 30 19:35:22 EDT 2012 TO 2.1-BETA0  Built On: Tue Jun 12 05:15:27 EDT 2012

      Regardless of the setting in the IPv6 DHCP6/RA page for "Router Advertisements" I only get it to advertise "Managed".  See below.

      I have tried to set both "Unmanaged" and "Assisted". No change.
      Have tried to halt/reboot system with "Unmanaged" set.  No change.
      Have disabled DHCP6 and removed "Use same settings as DHCPv6 server".  No change.

      I have even tried to set it to "Disabled" but I could still see Router Advertisments (with the Managed Setting)
      in my client originating from this router. (which I should not see when it is OFF)

      Seems like pfSense is stuck in "Managed" mode. :-/

      I have tried to change IP of the LAN interface and I could see this change in the RA message
      at the client so that part is working, but not changing Operating Mode for RA.

      Type: Router Advertisement (134)
         Code: 0
         Checksum: 0x7154 [correct]
         Cur hop limit: 64
         Flags: 0x80
      **       1… .... = Managed address configuration: Set**
             .0.. …. = Other configuration: Not set
             ..0. .... = Home Agent: Not set
             ...0 0... = Prf (Default Router Preference): Medium (0)
             .... .0.. = Proxy: Not set
             .... ..0. = Reserved: 0
         Router lifetime (s): 60
         Reachable time (ms): 0
         Retrans timer (ms): 0
         ICMPv6 Option (Prefix information : fd00:0:0:10::/64)
             Type: Prefix information (3)
             Length: 4 (32 bytes)
             Prefix Length: 64
             Flag: 0xa0
      **           1… .... = On-link flag(L): Set
                 .0.. .... = Autonomous address-configuration flag(A): Not set**
                 ..10 0000 = Reserved: 32
             Valid Lifetime: 86400
             Preferred Lifetime: 14400
             Reserved
             Prefix: fd00:0:0:10:: (fd00:0:0:10::)

      UPDATE: I reverted to the old build and it seems like RA is still seen even if OperatingMode = disabled.
      But now the different modes is working except disabled.
      Isn't this a bug?  When I set RA to disabled, shouldn't it be quiet and not send out RA ?

        I think I know what caused this, I tried to make it backwards compatible with the old mode field but have them reversed.
        Sorry.

          Hi,

          Thanks for the response. :-)

          Will the fix for working Operating mode be included in the tonight's build ?
          And also, when I set RA to Disabled, will it stop sending RAs ?

          Best regards

            Hard to tell what build has what, they take quite a while.

            And yes. Disabled means it should not send any advertisements

              Hi databeestje,

              Someone seems to have committed some fixes now. :-)

              I have tested all RA modes and they seem to send the correct flags and also when RA disabled it is quiet. :-)
