Hello,
I switched from legacy isc dhcp to the kea one in latest opnsense version.
I configured DHCP on IPv6. It is working on windows systems which get IP address, but unfortyunately Anbdroid phones do not get any ip v6 address.

Hello,
Did you solve your issue ?
It seems that I have the same issue : My PCs are getting IPv6 address while android phones fail to get one. Logs are showing the same.
regards,

Hello, this has been solved. I checked the disable firewall rules in the captive portal administration page. And created manually the rules.

Hello,
I upgraded to 26.1.6 and the captive portal doesn't work anymore.
The guest network is on its own VLAN, with own subnet (10.0.10.1).
If the captive portal is disabled, user can ping gateway (10.0.10.1), DNS server (192.168.10.18) and can go to the internet.
When captive portal is ON, everything is blocked. Gateway cannot be pinged, DNS server cannot be contacted, and poretal is not displayed (even when typing the address directly : http://10.0.10.1:8000).
Can you please help ?
Thanks,
Laurent.
