How to Use Dual Ethernet
Android’s dual Ethernet ports are divided into internal and external networks.
eth1(LAN1) : Secondary port, used for the internal network
eth2(LAN2) : Primary port, used for the external network
Checking the IP Address
When both Ethernet ports are connected to the network, you can check the IP address through the debug serial port or adb, for example.
