Hi all,

Firstly, I would like to thank Franco and his team for creating and continuously updating Opnsense, which is a great firewall for home users. Secondly, I just wonder if anyone notice that their Android devices cannot connect to the Internet after upgrading to Opnsense 24.7.6? I did the upgrade without changing anything (LAN IPs, firewall rules...) then realized that all my Android devices lost their Internet connection. However, other Apple and Windows ones still function properly.

My Opnsense is installed on an i5 computer with plugins of C-ICAP, Chrony, Crowdsec, KEA DHCP, Tayga and Zenarmor. Thank you in advance.




I've not seen any problems with my  Android devices, which include a Nexus 7 (2013) a Galaxy S6e and current models.

These are all on IPv4 networks.



I've been having issues with Android devices connecting over IPv6 since the "FreeBSD security advisory" patch and the back and forth with reverting it.

Thank you all for your reply! I think it is IPv6-related issue as I am using IPv6 from my ISP, and other Windows or Apple devices work flawlessly.
Thank you @GrantSquirt8415 for the link. I will give it a try and hopefully it would help for my problem.
