Security

Since the WorldLand network is a peer-to-peer network, it must be able to communicate with all nodes.

Default Port Settings

Protocol	Port	Description
P2P	`30303`	Peer-to-peer communication
HTTP-RPC	`8545`	HTTP JSON-RPC server
WS-RPC	`8546`	WebSocket JSON-RPC server

The P2P network is enabled by default. HTTP and WebSocket (WS) are disabled by default unless explicitly enabled with the corresponding flags.

Firewall Configuration

Required (P2P Network)

Allow TCP 30303 (or your custom port) — This allows nodes to connect to peers
Allow UDP 30303 (or your custom port) — This allows node discovery

JSON-RPC Security

Security Warning

When enabling RPC servers on WorldLand nodes, security must be taken into account. When a node allows external access, an attacker with an unlocked account can easily transfer the assets stored in the wallet.

See: How to reduce the chances of your wallet getting hacked

If enabling a JSON-RPC server:

Block all traffic to port 8545 (or your custom HTTP-RPC port) — except traffic from explicitly defined trusted systems
Block all traffic to port 8546 (or your custom WS-RPC port) — except traffic from explicitly defined trusted systems

Changing Ports

If you want to change the P2P port, see the port options in Command-Line Options:

bash

--discovery.port value   # (default: 30303) Use a custom UDP port for P2P discovery
--port value             # (default: 30303) Network listening port
--http.port value        # (default: 8545)  HTTP-RPC server listening port
--ws.port value          # (default: 8546)  WS-RPC server listening port
