How to Manage Your Linux or Windows VPS Firewall from the Client Area

Content

Overview

You can manage your Linux or Windows VPS firewall from the Client Area. Use Firewall in VPS Management to view, add, and delete firewall rules.

Incorrect firewall rules can interrupt SSH, Remote Desktop (RDP), websites, email, or other services. Before changing rules, identify the ports your services require and make sure you can access the VPS Console if your remote connection is interrupted.

1. Access Your VPS Service in the Client Area

Sign in to the Client Area.
Open Cloud Service from the menu or dashboard.
Choose your Linux or Windows VPS from the list.
Under Management, select Firewall.

The table displays each rule’s direction, IP version, protocol, port range, and remote IP address prefix.

2. Add a Firewall Rule

Click Add Firewall Rule.
Complete the fields in the Add Rule window:

Field	Description
Rule	Select Custom TCP Rule, Custom UDP Rule, Custom ICMP Rule, or Other Protocol.
Direction	Inbound controls traffic arriving at your VPS. Outbound controls traffic leaving it.
EtherType	Select IPv4 or IPv6 to match the address you are entering.
Open Port	For TCP or UDP, select Port, Port Range, or All Ports. Enter the relevant port numbers when prompted.
IP Address/IP Addresses Range	Enter the permitted remote address or network in CIDR format. This is the source for inbound traffic and the destination for outbound traffic.

For ICMP rules, complete the type and code fields displayed by the form.

CIDR examples:
203.0.113.10/32: one IPv4 address.
2001:db8::10/128: one IPv6 address.
0.0.0.0/0: any IPv4 address.
::/0: any IPv6 address.
The individual addresses above are documentation examples. Replace them with your actual addresses.

Review the rule.
Click Confirm.
Verify that the rule appears in the table.
Test the intended connection or service.

3. Examples: Allow Remote Access from Your IP Address

Use these examples to allow an inbound connection from your public IPv4 address:

Field	Linux: SSH	Windows: Remote Desktop
Rule	Custom TCP Rule	Custom TCP Rule
Direction	Inbound	Inbound
EtherType	IPv4	IPv4
Open Port	Port	Port
Port number	`22`	`3389`
IP Address/IP Addresses Range	Your public IPv4 address followed by `/32`	Your public IPv4 address followed by `/32`

If your service uses a custom port, enter that port instead.

A rule for your IP address does not restrict access while a broader rule still permits the same traffic from all addresses. Review existing Inbound / Any / Any / 0.0.0.0/0 and ::/0 rules.
Before removing broad rules, add the rules your services need and confirm that you have a recovery path.

The service must also be running and permitted by any firewall inside the operating system, such as Windows Defender Firewall or a Linux firewall. A Client Area firewall rule alone does not configure the service or the operating system firewall.

4. Delete a Firewall Rule

Find the rule you want to remove.
Click its trash icon.
Review the Delete Firewall Rule confirmation.
Click Delete to proceed or Close to cancel.
Verify that the rule is removed and test affected services.

To delete multiple rules, select their checkboxes and click Delete in the selection toolbar.

Review every selected rule before deleting. Removing inbound rules may block remote access or public services. Removing outbound rules may prevent your VPS from reaching required external services.
