To configure a firewall rule:
- Go to your Cloud menu.
- Click the label of the machine to which you want to configure a firewall rule.
- Click the Network -> Firewall tab.
- On the page that appears set the following: - Choose the network interface. - Specify if the rule defines requests that should be accepted or dropped. - Set the IP address for which this rule is active. - Leave the empty field to apply this rule to all IPs - Enter hyphen-separated IPs to apply the rule to an IP range (e.g. 192.168.1.1-192.168.1.10) - Enter the IPs with slash to apply the rule to CIDR (e.g. 192.168.1.1/24) - Set the port for which this rule is effective. - Leave the empty field to apply the rule to all ports - Enter colon-separated ports to apply the rule to a port range (e.g. 1024:1028) - Enter comma-separated ports to apply the rule to the list of ports (e.g. 80,443,21) - Choose the protocol (TCP or UDP).
- Save the rule.
The Int1 ACCEPT 122.158.111.21 22 TCP firewall rule means that the Int1 network interface will accept all the requests and packets addressed from a 122.158.111.21 IP using TCP protocol on a 22 port. The Int2 DROP 122.158.111.21 22 UDP firewall rule means that the Int2 network interface will reject all the requests and packets running from a 122.158.111.21 IP using TCP protocol on a 22 port.
Because some rules can override each other, it is important to set the order in which they are processed. Use the up/down arrows next to a rule to set priority.
Expected result
- The product behaves as described in each step (connectivity, message, or UI state).
If something goes wrong
- Repeat the step and check for typos (hostnames, passwords, ports).
- Note the exact error message or screenshot.
- Open a ticket in the Boxis client area with the service name, time of the test, and any trace (e.g. traceroute) if it is a network issue.
