@Gertjan, thanks to awnser.

The problem is in captive portal WebServer.

That
http://192.168.8.1:8002/index.php?zone=vistantes&redirurl=http://.......
it was you entered that URL or did you get it from the captive portal web server ?

That URL is created here :
/var/etc/nginx-vistantes-CaptivePortal.conf - line 45.
That file is the main config file of the captive portal http web server, listing on port 8002.

The pf firewall redirects all http (destination port 80) to the "interface IP" port 8002.
From there on, the captive portal web server takes over.

Can you show :

sockstat -4 | grep '8002'

Can you show :

sockstat -4 | grep '8002'

?

Btw : You and I have the same "/var/etc/nginx-XXXXXX-CaptivePortal.conf" file. Only the name of the zone changes.

Probably not related, but this seems strange to me :

error_log /dev/null;
error_log  syslog:server=unix:/var/run/log,facility=local5;

You can use Diagnostics Packet Capture on your VLAN_50_GUEST interface, port 8002, protocol TCP.

192.168.8.1 is a /24 network, right ?
DHCP 192.168.8.1/24 is ok ?

What happens when you remove your firewall rule and put this rule in place :

where LAN address = VLAN_5_GUEST address.

Are you using the default Netgate login page ?
What happens when you use the Live view and View page content buttons :

rec

@Gertjan, thanks again.

sockstat -4 | grep '8002'

The VLAN_50_GUEST / 24

DHCP / 24

pfSense Rule VLAN_50_Guest
I changed to accept all the trafic, from all the interfaces. Continious the same error.
I deleted and recreate the rule.

DEFAULT NETGATE LOGIN PAGE
When I remove the custom loggin page, I have the same error.

rec

@Gertjan, today I update to 2.7.1 version, the problem continues. Regards.

rec

@Gertjan, result of "Packet Capture".

@Gertjan, I found the problem!

Is my UBIQUITI Wi-Fi configuration.

When I marked this option the "GUEST Wi-Fi" isolate the client.

.

The problem has been solved.

Thanks a lot.

Regards.
