Captive Portal bypass issue
-
@marcosm understood. Will follow up tonight and respond back here.

@michmoor Well cant reproduce my issue. I truly dont get it. The things i tried tonight.
- Radius auth as always. MAC bypass with PASS. Unable to browse other vlans. Internet access is fine.
- Radius auth as always. MAC bypass with block. Still able to sign-in but unable to browse other vlans. Internet access is fine.
- No auth. MAC bypass with block. Still able to sign-in but unable to browse other vlans. Internet access is fine.
The only significant change made from when the issue was reported to now is that pfblockerNG is set up for bypass for the whole /24 Guest range. I dont think pfblcoker is in anyway related but wanted to be transparent with what changed for the guest vlan.
Other than that, i cant explain why the rules are working now but they were not working before as i shown in the pictures above. I will continue to test with different devices. -
These two :

No auth. MAC bypass with block. Still able to sign-in but unable to browse other vlans. Internet access is fine.That is the "MAC block" not working issue. You are using 22.05 ?

That is IPv6 traffic hitting the IPv4 Limiters
It's fixed in 23.01: https://redmine.pfsense.org/issues/13290

@stephenw10 Confirmed. Kicked off a iPhone client on the captive portal and those messages are gone.

...a) pointing out this "problem"
...b) having a discussion about it
...c) trying to reproduce the issue

Seriously: thanx for your ongoing support and (my personal opinion) the good work with pfsense so far...hope Santa has you on his list. -
The MAC address block entries now work as expected with the newly added patch.

@stephenw10 @marcosm
Thanks gents. I couldnt find the commitID.
I can confirm that this is fixed. The mac addresses not only cannot get on the network but there is a message indicating to the client that they are blocked.Also syslogs confirms block
I really dont know what to say but this has been a journey in troubleshooting and talking to the netgate team. Truly appreciate it.
Time to whip out the old wallet for that TAC sub

Euh .... the solution was already on the forum.
13747 went from Not a bug, to Duplicate, to Bug again to get solved. I guess it's a question of finding the right words when writing feedback.The official patch, as always, is much nicer : why adding a line if removing something does the job
And be careful : https://redmine.pfsense.org/issues/13784 was added on the fly : A MAC can (23.01) be blocked the soft way, the user will see the message that his MAC is blocked. You can chose bewteen an error message, or a MAC block portal page to be uploaded. See here for info and example how to implement that.
Or : new, see 13784 : totally rejected : the MAC becomes part of the pf rules that block any interaction with the captive portal interface. I guess the user would be able to get a DHCP lease sorted out, and that's it, nothing more.
