Seems the issue comes with an incorrect/mismatching GRUB configuration: The connection tracking feature does not work if:
in the /etc/default/grub The GRUB_DEFAULT="Debian GNU/Linux. with Linux 6.1.0-27-amd64" But The system actually boots the 6.1.0-28 kernel, If the GRUB_DEFAULT entry is changed to GRUB_DEFAULT="Debian GNU/Linux. with Linux 6.1.0-28-amd64" The issue seems to resolve. - Always starting the default entry On Tue, Dec 17, 2024 at 11:45 AM Debian Bug Tracking System < [email protected]> wrote: > Thank you for the additional information you have supplied regarding > this Bug report. > > This is an automatically generated reply to let you know your message > has been received. > > Your message is being forwarded to the package maintainers and other > interested parties for their attention; they will reply in due course. > > Your message has been sent to the package maintainer(s): > Debian Kernel Team <[email protected]> > > If you wish to submit further information on this problem, please > send it to [email protected]. > > Please do not send mail to [email protected] unless you wish > to report a problem with the Bug-tracking system. > > -- > 1090183: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1090183 > Debian Bug Tracking System > Contact [email protected] with problems >
