I would like to report a issue on a fresh KDE-neon install.
Installed Firewalld (0.4.4.5) and disabled the defaut firewall (ufw).
BTW, this firewall should be installed by default, along Kleopatra, Sementik, Kate and Ksystemlog.

Right out the box, the CIFS/samba stack is not going through the firewall. Whatever firewall I used, the target (Synology NAS) is not going through.
The discovery of the network returns a limitation by the firewall. (Dolphin 20.04.0. KDE framework 5.70, Qt 5.14.2)

# Post depreciated due to improper bios setting.
Sorry
