Installation

Please note: When you installed syncthing using the official deb package, you can skip the copying.

Copy the file syncthing to your ufw applications directory usually located at /etc/ufw/applications.d/. (root permissions required).

Then run

sudo ufw app update syncthing

to load the preset. To allow the syncthing ports, run:

sudo ufw allow syncthing

You can also verify the opened ports:

sudo ufw status verbose
