Gyro Cloud Istanbul: network firewall and security groups (open SSH only to your IP)

Q: What if I do not buy the add-on?

The server is open to the internet; use ufw or similar inside the server to protect it. Without the add-on, security groups cannot be written through the API.

Who this is forAnyone who wants the server reachable only on the ports it needs.

What you needAn active Gyro Cloud Istanbul server and to know the IP address you connect from (the panel suggests it).

1. What does it do and what does it cost?

The Network Firewall filters traffic at the network edge before it reaches your server; it is independent of the ufw or iptables settings inside the server. You can open SSH only from your office and open web ports to everyone.

It is added as an add-on. On a prepaid server it is charged hourly (monthly price 0.99 €; hourly = monthly ÷ 672, excluding VAT, TRY at the current rate). The add-on appears as a separate item on the Spending page.
An extra rule pack and a blocked-traffic report are optional add-ons (Network Firewall guide).
When the server is deleted the add-on ends too.

Info

You can use ufw inside the server even without the Network Firewall. The add-on is for stopping traffic in the network before it reaches the server and for managing rules from the panel/API.

2. Adding the add-on

On a new order: tick Network Firewall in the add-ons list on the order screen.
On an existing server: open the Firewall tab on the service page; the Add as add-on button takes you to the Add-ons tab. Choose the add-on and confirm. The cost is deducted hourly from your balance; the tab turns into the rule screen.

3. Open SSH only to your IP

On the Firewall tab click the Linux management preset.
In IP addresses to allow the IP you are connecting from is filled in. Add your office and home IPs separated by commas.
If you have a website, add the Web preset too (HTTP/HTTPS open to everyone).
Press Save and try. The status shows Applying for a few seconds and then Trial; a 5-minute countdown starts.
Without closing your current SSH session, try connecting from a new window and open your site.
If all is well press Make permanent. If you cannot connect do nothing: after 5 minutes the change is rolled back automatically.

Warning

If your IP address changes (home internet, mobile), allowing only that IP can lock you out. In that case connect from a fixed IP (office) or a VPN exit, or use the console (VNC console).

4. Security groups

A security group is a reusable allow list you write once and attach to several servers (for example a "Web" group: 80 and 443; a "Management" group: 22 from your office IP). Up to 5 groups can be attached per server. A security group has allow rules only; incoming traffic is closed if no rule allows it. Details: Network Firewall guide.

bash

gyro security-group list
gyro security-group create --help
gyro security-group attach --help
gyro server firewall list 12345

5. Frequently asked questions

I locked myself out; what should I do?

If you are in trial mode wait 5 minutes; the change is rolled back. If you made it permanent press Emergency open in the panel or sign in through the VNC Console and fix it (Locked out, emergency open).

What if I do not buy the add-on?

The server is open to the internet; use ufw or similar inside the server to protect it. Without the add-on, security groups cannot be written through the API.

How do I stop the charge?

You can remove the add-on or delete the server; the add-on is charged hour by hour.
