Fixed IP Plan / Firewall Configuration
This page provides instructions on how to view, add, and delete firewall rules on a VPS with a fixed IP plan.
Firewall configuration changes should only be made after understanding the fundamentals of network protocols and ports.
Implementing settings without understanding them may create security vulnerabilities, allowing malicious third parties to use your VPS as a stepping stone, which could result in liability for damages.
Please ensure you understand the above and operate responsibly.

Select the interface to which the rule should apply.
2. Type #
Select inbound (IN) or outbound (OUT).
3. Action #
Choose to allow (ACCEPT), drop (DROP), or reject (REJECT).
4. Protocol #
Select the network protocol to be used.
5. Source / Port #
Restrict the source IP address and port number making the inbound request.

After configuration, click the Submit button to apply the rule.
Use this example as a reference to configure your rules. If you have any questions, open a support ticket.
8. Deleting a Rule #
Step 4 Delete unnecessary existing rules #
If you have configured a rule in section 7 that restricts the source IP address, you may need to delete the existing rule that allows RDP requests from all IP addresses as needed.
- Click the Delete button at the right end of the target rule row.
- A final confirmation will appear; if everything is correct, click OK.
Deleting rules in the wrong order may prevent Remote Desktop connections. Ensure the connection restriction rule has been properly added before deleting the existing rule.
