🚀 Basic Usage

Quick Networking with Shared Nodes

EasyTier supports quick networking using shared public nodes. When you don't have a public IP, you can use the free shared nodes provided by the EasyTier community. Nodes will automatically attempt NAT traversal and establish P2P connections. When P2P fails, data will be relayed through shared nodes.

When using shared nodes, each node entering the network needs to provide the same --network-name and --network-secret parameters as the unique identifier of the network.

Taking two nodes as an example (Please use more complex network name to avoid conflicts):

1. Run on Node A:

# Run with administrator privileges
sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<SharedNodeIP>:11010

2. Run on Node B:

# Run with administrator privileges
sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<SharedNodeIP>:11010

After successful execution, you can check the network status using easytier-cli:

| ipv4         | hostname       | cost  | lat_ms | loss_rate | rx_bytes | tx_bytes | tunnel_proto | nat_type | id         | version         |
| ------------ | -------------- | ----- | ------ | --------- | -------- | -------- | ------------ | -------- | ---------- | --------------- |
| 10.126.126.1 | abc-1          | Local | *      | *         | *        | *        | udp          | FullCone | 439804259  | 2.6.2-70e69a38~ |
| 10.126.126.2 | abc-2          | p2p   | 3.452  | 0         | 17.33 kB | 20.42 kB | udp          | FullCone | 390879727  | 2.6.2-70e69a38~ |
|              | PublicServer_a | p2p   | 27.796 | 0.000     | 50.01 kB | 67.46 kB | tcp          | Unknown  | 3771642457 | 2.6.2-70e69a38~ |

You can test connectivity between nodes:

# Test connectivity
ping 10.126.126.1
ping 10.126.126.2

Note: If you cannot ping through, it may be that the firewall is blocking incoming traffic. Please turn off the firewall or add allow rules.

To improve availability, you can connect to multiple shared nodes simultaneously:

# Connect to multiple shared nodes
sudo easytier-core -d --network-name abc --network-secret abc -p tcp://<SharedNodeIP1>:11010 -p udp://<SharedNodeIP2>:11010

Once your network is set up successfully, you can easily configure it to start automatically on system boot. Refer to the One-Click Register Service guide for step-by-step instructions on registering EasyTier as a system service.

Decentralized Networking

EasyTier is fundamentally 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. Here's how to set up a decentralized network:

1. Start First Node (Node A):

# Start the first node
sudo easytier-core -i 10.144.144.1

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

• TCP: 11010
• UDP: 11010
• WebSocket: 11011
• WebSocket SSL: 11012
• WireGuard: 11013

2. Connect Second Node (Node B):

# Connect to the first node using its public IP
sudo easytier-core -i 10.144.144.2 -p udp://FIRST_NODE_PUBLIC_IP:11010

3. Verify Connection:

# Test connectivity
ping 10.144.144.2

# View connected peers
easytier-cli peer

# View routing information
easytier-cli route

# View local node information
easytier-cli node

For more nodes to join the network, they can connect to any existing node in the network using the -p parameter:

# Connect to any existing node using its public IP
sudo easytier-core -i 10.144.144.3 -p udp://ANY_EXISTING_NODE_PUBLIC_IP:11010

🔍 Advanced Features

Subnet Proxy

Assuming the network topology is as follows, Node B wants to share its accessible subnet 10.1.1.0/24 with other nodes:

flowchart LR

subgraph Node A Public IP 22.1.1.1
nodea[EasyTier<br/>10.144.144.1]
end

subgraph Node B
nodeb[EasyTier<br/>10.144.144.2]
end

id1[[10.1.1.0/24]]

nodea <--> nodeb <-.-> id1

To share a subnet, add the -n parameter when starting EasyTier:

# Share subnet 10.1.1.0/24 with other nodes
sudo easytier-core -i 10.144.144.2 -n 10.1.1.0/24

Subnet proxy information will automatically sync to each node in the virtual network, and each node will automatically configure the corresponding route. You can verify the subnet proxy setup:

1. Check if the routing information has been synchronized (the proxy_cidrs column shows the proxied subnets):

# View routing information
easytier-cli route

2. Test if you can access nodes in the proxied subnet:

# Test connectivity to proxied subnet
ping 10.1.1.2

WireGuard Integration

EasyTier can act as a WireGuard server, allowing any device with a WireGuard client (including iOS and Android) to access the EasyTier network. Here's an example setup:

flowchart LR

ios[[iPhone<br/>WireGuard Installed]]

subgraph Node A Public IP 22.1.1.1
nodea[EasyTier<br/>10.144.144.1]
end

subgraph Node B
nodeb[EasyTier<br/>10.144.144.2]
end

id1[[10.1.1.0/24]]

ios <-.-> nodea <--> nodeb <-.-> id1

1. Start EasyTier with WireGuard portal enabled:

# Register one WireGuard client as virtual peer 10.144.144.3
sudo easytier-core -i 10.144.144.1 \
  --network-secret portal-secret \
  --vpn-portal wg://0.0.0.0:11013 \
  --vpn-portal-private-key "$(wg genkey)" \
  --vpn-portal-client phone=10.144.144.3

2. Get WireGuard client configuration:

# Get WireGuard client configuration
easytier-cli vpn-portal

3. In the output configuration, replace a wildcard Peer.Endpoint with the public IP/domain of your EasyTier node, then import it. Interface.Address is local to that WireGuard client and may be changed to any IPv4 address; EasyTier translates it to the registered virtual-peer address.

Self-Hosted Public Shared Node

You can run your own public shared node to help other nodes discover each other. A public shared node is just a regular EasyTier network (with same network name and secret) that other networks can connect to.

To run a public shared node:

# No need to specify IPv4 address for public shared nodes
sudo easytier-core --network-name mysharednode --network-secret mysharednode
