1 – Firewall
CyberPanel follows deny all rules except for the ports opened by default, you can see default opened ports at: Server > Security > Firewall
Add Firewall Rule
As I’ve mentioned above, CyberPanel follows deny all rules, so if you want to allow any port you can add from Server > Security > Firewall.
Give this rule a name.
Select protocol from dropdown either tcp or udp.
Enter which port to open for specified protocol.
This will add rule and reload firewall.
Delete Firewall Rule
Just click on the cross on right side of the rule, this will delete the rule and reload firewall.
