6.2 Router Port Arrangement
To expose your node’s open ports to the internet, you must forward them on your home router. This allows external peers to connect through your network’s public IP and reach your node’s static IP and ports.
tip
Additionally to opening the router ports, you must configure the Firewall Settings of your node to allow data throughput.
info
You will have to know both IP and MAC addresses from the Router Setup to identify your node while configuring the router.
1. Log into the Router
In a browser, navigate to your router’s admin interface and log into your router's dashboard with its admin credentials.
info
The following steps are performed on your 💻 personal computer.
note
Router interfaces are typically located at 192.168.0.1, 192.168.1.1 or 192.168.178.1.
2. Add Port Forwarding Rules
2.1 Navigate to Port Forwarding: In your router's web interface, navigate to the firewall or port forwarding settings.
Fritzbox Router
Navigate to Internet > Permit Access > Port Sharing
2.2 Select the Device: Select or configure your node device to create new port forwarding rules.
Fritzbox Router
Port Sharing > Add Device for Sharing
---------------------------------------------------------------------------------
| DEVICE: <device-name> |
| IPV4 ADDRESS: <ip-address> |
| MAC ADDRESS: <mac-address> |
| IPV6 INTERFACE ID: <ipv6-interface-id> (assigned automatically) |
---------------------------------------------------------------------------------
| □ Permit independent port sharing for this device |
---------------------------------------------------------------------------------
| IPV4 |
| □ Open this device completely for internet sharing via IPv4 (exposed host) |
---------------------------------------------------------------------------------
| IPv6 |
| Enable PING6 |
| Open firewall for delegated IPv6 prefixes of this device |
| Open this device completely for internet sharing via IPv6 (exposed host) |
---------------------------------------------------------------------------------
info
The <device-name>, <ip-address>, <mac-address>, and <ipv6-interface-id> will reflect your node's properies.
2.3 Add Execution Port Forwarding Rules: Set multiple port access rules for UDP and TCP connections.
RULE 1
-------------------------------------------------------------------------
| NAME: execution-tcp-30303 |
| PROTOCOL: TCP |
| PORT TO DEVICE: 30303 THROUGH PORT: 3030 |
| PORT REQUESTED EXTERNALLY: 30303 |
| (IPv4 only) |
-------------------------------------------------------------------------
| ⊠ Enable sharing |
-------------------------------------------------------------------------
| IPV4 ADDRESS IN THE INTERNET: <internet-ip-address> |
| PORT ASSIGNED EXTERNALLY: 30303 THROUGH PORT: 3030 |
-------------------------------------------------------------------------
RULE 2
-------------------------------------------------------------------------
| NAME: execution-udp-30303 |
| PROTOCOL: UDP |
| PORT TO DEVICE: 30303 THROUGH PORT: 3030 |

| PORT REQUESTED EXTERNALLY: 13000 |
| (IPv4 only) |
-------------------------------------------------------------------------
| ⊠ Enable sharing |
-------------------------------------------------------------------------
| IPV4 ADDRESS IN THE INTERNET: <internet-ip-address> |
| PORT ASSIGNED EXTERNALLY: 13000 THROUGH PORT: 13000 |
-------------------------------------------------------------------------
RULE 4
-------------------------------------------------------------------------
| NAME: consensus-udp-12000 |
| PROTOCOL: UDP |
| PORT TO DEVICE: 12000 THROUGH PORT: 12000 |
| PORT REQUESTED EXTERNALLY: 12000 |
