Step 7. Add a firewall rule to accept remote access of SSH port. For example:
if the remote access IP is 110.5.14.6 and the port is 8022.
Note: If the remote access of SSH port is not needed, this rule is not required.
Name: RemoteSSH
Protocol: TCP
Port: 8022:8022
IP: 110.5.14.6/255.255.255.255
Action: Accept

Step 8. Add other firewall rules by yourself. For example, if you are using
features related to email, you should add the firewall rules for the SMTP server
and POP3 server.
Step 9. Enable Drop all (If this feature is enabled, all the packets and
connection that do not match the rules would be dropped.)
Note: Before enable this feature, please add a rule to accept the local network
access, or the server might not be accessed.
