Use FreeBSD 15.0-CURRENT as your base system for building the package.
git clone [email protected]:netbirdio/pfsense-netbird.git
cd pfSense-pkg-NetBird/
make
make package
The make package command will generate a file like:
/work/pkg/pfSense-pkg-NetBird-<version>.pkg
You can then transfer this file to your pfSense system and install it manually.
To install the package manually on pfSense:
pkg add netbird-<version>.pkg
pkg add -f pfSense-pkg-NetBird-<version>.pkg
Once installed, NetBird will appear under the VPN menu in the pfSense Web UI.
