Hello,
It appears to be a good idea to set up a firewall on linux. Ufw seems to be an easier way of doing so on my server. I am wondering if there are considerations that I am too inexperienced to know about it's interaction with OMV5. Did a check in search in the forum and I didn't locate anything that seem relavent to my questions. I have set up a user with sudo permission and changed the port for ssh. A lot of info on youtube that it is further confusing.
Thanks for any assistance.
