Firewall allows users to open and close ports on the server. The server opens ports 22 (for SSH service), 80 (for HTTP service), and 443 (for HTTPS encrypted access service) by default. The rest ports are closed by default.
Log on to the Simple Application Server console, and select Security > Firewall > Add Rules.
Select the corresponding application type, protocol, and port number, and then click OK.
If you want to add more rules, you can click Add rules.
The firewall has pre-installed the mapping relations between the following applications and port numbers.
|HTTP||TCP||80||Default port for HTTP protocol|
|HTTPS||TCP||443||Default port for HTTPS encryption protocol|
|SSH||TCP||22||Default port for SSH protocol|
|FTP||TCP||21||Default port for FTP protocol|
