I just spun up a private instance of lemmy on the cheapest Linode. So far so good.
I used the ansible method of installing the instance on the default Debian 11 image from Linode (link below).
I feel a bit worried that there are no firewall instructions in the install documents. And no notes on securing your instance.
Any thoughts on how to set up ufw for a lemmy instance? Or thoughts on other security tips?
Also consider changing the port for SSH to some random port >1024 and maybe install fail2ban for good measure.
