I’m using the cyberpanel to host my site ONLY… I don’t intend to use an email server or DNS. based on that:
What port I can disable on the CSF firewall which is not needed, like 465, 993, or 995? and please advise which ones I should keep for OpenLiteSpeed and http/s… knowing no emails and no DNS.
Shall I remove those ports mentioned in step 1, from TCP in/out and UDP in/out?
443 → to use https
8090 → to access cyberpanel
22 → to ssh to the server (console)
21, 40110:40210 → If you let your users have FTP access. If you are the only person managing the websites, just delete this and use ssh if you wanna edit/upload something.
You can find a full list of ports here for reference:
