Fedora includes and enables firewall rules set by default. I mean –as an end user opinion– it’s not the same as Ubuntu. When I was using Ubuntu, everything just works, no hassle caused by firewall. Then when the first time I tried Fedora, there are a few restrictions created by firewall configuration. I’m not really understand firewall, though. But soon I learnt it.
TL;DR, at least I’ve got 3 hurdles in dealing with Fedora firewall default config. They are blocked by the config, i.e
- Samba Share
- KDE Connect
- VLC UPNP / DLNA
By then, I put them as whitelist apps to be allowed in the Firewalld config manager. Then this day, I look again, and actually I totally disable the firewalld of systemd.
sudo systemctl disable firewalld
