1.2 Quick Start: Connecting Your Device
Method 1: Connect your PC to the device’s LAN port using an Ethernet cable.
Since the device’s LAN port has a default IP of 192.168.88.1. You need to set your PC’s IP address to the same subnet (e.g., 192.168.88.x), as shown below:

Method 2: Connect your PC to the device’s hotspot via WiFi.
Once connected, the device will assign your PC an IP address in the 192.168.88.x subnet, as shown:

💡Note: The EC100 series does not have WiFi, so it cannot be connected via WiFi.

💡Once the settings are complete, click Submit to apply.
2.4.1 Basic

Basic:
-
Enable: Whether to enable the network setup function
-
Node Name: Used to distinguish devices within the network. Ensure that node names are unique within the same network.
-
DHCP: If enabled, virtual IPs are automatically assigned to gateways. It is recommended to set static virtual IPs.
-
Node IP: The gateway’s virtual IP within the network.
-
Network Name: Customizable. Must be the same for all nodes within the same network (length 6–127).
-
Network Password: Customizable. Must be the same for all nodes within the same network (length 6–127).
Subnet Proxy:
Configuration Instructions:
-
Access a Single Device:
To remotely access a device in the local LAN with IP 192.168.0.55:
→ Configure: 192.168.0.55/32 → Mapped IP (leave blank)
-
Access the Entire Subnet:
To remotely access all devices in the local LAN with IP range 192.168.0.X:
→ Configure: 192.168.0.0/24 → Mapped IP (leave blank)
-
Resolve IP Conflicts (Mapping Mode):
If both ends of the network have the same LAN IP range, use IP mapping to avoid conflicts by mapping the target IP to a new range.
→ Configure: 192.168.0.10/32 → Mapped IP: 192.168.1.10
The remote node can then access the device with LAN IP 192.168.0.10/32 via 192.168.1.10.
Advanced:
-
IPv6: Disable IPv6; only IPv4 is used for communication.
-
Latency Priority Mode: Prioritize the path with the lowest total latency, ignoring intermediate hops.
-
User-Space Protocol Stack: Use a user-space TCP/IP stack to avoid OS firewall issues that may block subnet or KCP proxy.
-
KCP Proxy: Converts TCP traffic to KCP to reduce transmission latency and improve speed.
-
Disable KCP Input: Disable inbound KCP traffic; other nodes using KCP will still connect via TCP.
-
Enable QUIC Proxy: Converts TCP traffic to QUIC to reduce latency and improve speed.
-
Enable Exit Node: Allows this node to act as an exit node.
-
Enable Encryption: Must match peer nodes if encryption is disabled.
