comment Whats a secure firewall rules using UFW?
Unfortunately my home connection is dynamic, so I will have to look at netblock whitelist option. I can ask my backup service for a list of ip address I can whitelist for ftp server. Interesting, never thought of it, should be able to block nginx, page is server via varnish. Mail is MX for a domain, but only used to receive alerts and logs to my personal email. Thanks, your answer is very helpful.

Thanks for your answer, its a vps webserver hosting a website, intended for public. Port 80 and 8080 is webserver related nginx/varnish. 6698 is SSH server for me to connect from home.25 is mail and 9939 is for ftp for automatic backup with limited user access, auto backup service I am using doesn't use anything other than ftp. I am trying to figure out if firewall can provide extra layer of protection on these open services.

comment How does a firewall help to protect a server?
After an initial bout of negative votes for what I thought was a legitimate question, I got discouraged and never checked back. Just got an email notification. Your answer helped me understand the role of firewall more clearly. Thanks for the explanation.
