Decentralized Networking

Most networking software is centralized, where all devices must connect to a central server to form a network.

EasyTier is decentralized, with no distinction between server and client. As long as one device can communicate with any node in the virtual network, it can join the virtual network.

Two-Node Networking

Assume the network topology of two nodes is as follows:

Steps

1. Run the following command on Node A:

   sudo easytier-core -i 10.144.144.1

   • -i specifies the virtual network IP address.

   After startup, this node will listen on the following ports by default:

   Protocol	Default Port
   TCP	11010 (TCP)
   UDP	11010 (UDP)
   WebSocket	11011 (TCP)
   WebSocket SSL	11012 (TCP)
   WireGuard	11013 (UDP)

   You can specify listening ports through the -l parameter, for example:

   Parameter Example	Description
   -l 12345	Change the base port to 12345, then listening ports are: TCP: 12345, UDP: 12345, WebSocket: 12346, WebSocket SSL: 12347, WireGuard: 12348
   -l tcp:11010 -l udp:11011	Change TCP port to 11010, UDP port to 11011, only listen on these two ports. Supported protocols are tcp, udp, ws, wss, wg
   --no-listener	Disable port listening, which will affect the establishment of non-hole-punching connections.

2. Run the following command on Node B:

   sudo easytier-core -d -p udp://22.1.1.1:11010

   • -d represents DHCP mode, automatically assign virtual IP.
   • -p specifies the public address and port of Node A.

Three-Node Networking

Based on two-node networking, the third node C can join the virtual network by connecting to Node A or Node B.

Assume networking by connecting to Node A, the network topology is as follows:

Steps

1. Run the following command on Node C:

   sudo easytier-core -d -p udp://22.1.1.1:11010

   • -d represents DHCP mode, automatically assign virtual IP.
   • -p specifies the public address and port of Node A.

Subsequently, Node C can communicate with Node A and Node B through the virtual network.
