Captive Portal?

[AndyX90]

Hey guys,
i have a problem setting up OPNSense 17.1.2 with captive portal including transparent proxy and custom blacklist.
On my OPNSense Box there are 3 interfaces - WAN 100MBit and LAN 1GBit and WiFi 1GBit. On WiFi Interface there are 5 APs connected via ethernet.
I did enable Webproxy on int. WIFI in transparent mode, enabled SSL filtering (only block ips/domains) and inserted my blacklist with ~ 20 entries.(auth backend - local for testing). After that i enabled the captive Portal for int. WIFI and checked the 2 transparent proxy redirect options(http/https). But now when clients connect to the wifi, the portal page doesn't come up if i open websites in the browser. Internet traffic is possible but without portal page. Also no automatic notifications for WiFi-Authentication (in this case on android clients) are displayed.
Is it necessary to make nat-rules for redirecting traffic for http/https or is this done by those captive portal options automatically/internally?
Also i followed this partially but without success.

Any help would be appreciated.

If you are using the Captive Portal on 17.1.x, you should try it without the firewall NAT rules (if the forwarding is done in the captive portal).
