The default firewall configuration of Oracle Linux in the OCI environment basically denies everything. To enable traffic of any kind these following commands are needed.
sudo systemctl status firewalld
sudo firewall-cmd --list-all
sudo firewall-cmd --zone=public
sudo firewall-cmd --zone=public --add-port=5201/tcp --permanent
sudo firewall-cmd --zone=public --add-port=5201/udp --permanent
This worked for me. It will probably work for you with minor touches if you insist. After I ran this for a while I didn't like how unreliable Duplicati was with the actual work of backing up and I began to investigate Duplicacy instead. I will leave this here for a year or so because it will probably remain more or less valid for that long and I did spend a lot of time putting it together to just thwack it because it's not useful to me. YMMV. GL. GG.
This is a note on installing Duplicati, a free Backup server into a TrueNAS Core jail.
In TrueNAS create a Jail running the latest FreeBSD image available (13.2-RELEASE-p4). I am calling this jail instance backup
