Port Forwarding & Firewall

Overview​

This guide explains how to configure network settings and set up port forwarding for Autonomys Network. Correct port forwarding is essential to ensure proper communication between your node, farmer, and the Autonomys Network.

By opening specific ports on your router, you allow external traffic to reach your node, which is necessary for blockchain synchronization, data exchange, and remote procedure calls (RPC).

Additionally, you may need to adjust your system's firewall settings to allow traffic through the specified ports. Firewalls typically block unsolicited incoming connections, so it's important to ensure that the required ports are open. These adjustments will enable effective communication with the Autonomy Network.

Ports to Forward & Firewall Access​

Multiple Node Configuration

Ensure each node on the same network runs on unique ports. Adjust the ports mentioned in this guide if using multiple nodes or if default ports have been changed.

Exposing RPC Ports

For security reasons, RPC ports 9944 and 9945 should never be exposed to the internet via port forwarding unless you're operating a public RPC server. However, if the node and farmer are on different computers on the same network, these ports should be allowed through the firewall on the node.

Steps to Forward Ports​

Since the port forwarding process varies by router, follow these general steps:

  1. Find Your Router’s IP Address: Check your network settings to locate your router’s IP address. You will also need the internal IP address of the computer running the Autonomys components.

  2. Access Router Settings: Open your router’s settings by entering the router's IP address into a web browser. You may need the default login credentials, often printed on the router or provided by your ISP.

  3. Set Up Port Forwarding: In the router's configuration interface, navigate to Advanced Settings or Port Forwarding and enter the following details:

    • The internal IP address of your computer
    • Consult the tables above for the ports and protocols that need to be forwarded (30333, 30433, 30533, etc.).

    Once entered, apply the changes and reboot your router if necessary.

Manufacturer instructions​

Here are the links to port forwarding guides from five major consumer router manufacturers:

TP-Link

You can configure port forwarding through the "Forwarding" section on the router's web interface. You'll add a new rule under "Virtual Servers" and specify the device and ports you want to open. TP-Link Port Forwarding guide

Netgear

On Netgear routers, port forwarding is set up by navigating to the "Advanced Setup" section and selecting "Port Forwarding/Port Triggering." Netgear Port Forwarding guide

Linksys

Log in to your router’s web interface and configure port forwarding under the "Apps and Gaming" section of the "Security" tab. Linksys Port Forwarding Guide

ASUS

On ASUS routers, port forwarding is set up via the "WAN" tab, where you’ll find the "Virtual Server/Port Forwarding" option. ASUS Port Forwarding Guide

D-Link

For D-Link routers, port forwarding is done in the "Advanced" tab under "Port Forwarding." You’ll add a rule and enter the necessary details. D-Link Port Forwarding Guide

Firewall Configuration​

🐧 Linux Advanced CLI (Farmer)

If you are using Linux with UFW (Uncomplicated Firewall) enabled, you will need to allow traffic on the necessary ports to ensure your node and farmer can communicate properly. Use the following commands to update your firewall settings:

Allow node traffic on ports 30333 and 30433:
sudo ufw allow 30333,30433 comment 'Autonomys Node'
Allow farmer traffic on port 30533:
sudo ufw allow 30533 comment 'Autonomys Farmer'
If you are connecting remote farmers within your local network (LAN), allow RPC connections by running this command (assuming your LAN IP range is 192.168.1.0/24):
sudo ufw allow from 192.168.1.0/24 to any port 9944 proto tcp comment 'Autonomys Node RPC'

Network Configuration Scenarios​

ScenarioRequired Action
Using a RouterEnsure that the necessary ports are properly forwarded to the machine running your services.
FirewallConfigure your firewall settings to ensure the required ports are open for incoming and outgoing traffic.
No FirewallNo additional configuration is necessary if a firewall is not in use.
Direct Internet ConnectionIf you are connected directly to the internet without a router, no port forwarding is required.
