fff in dieser Verzeichnissstruktur ist meines wissens die Community, da 
gibts irgendeine Variable dafür. Es müsste VPN_PROJECT aus 
/etc/community.cfg sein. Sollte man wohl so wie hier lösen:

das gleiche hier

> +		broker=yes
> +		#write l2tp config
> +		fdport=$(greo ipv4 /etc/fastd/fff/peers/$peer | cut -f5 -d " " | tr -d \;)
hier ebenfalls, dazu soll das wohl grep anstatt greo sein oder?
