Dual LAN interfaces for three network working modes
Multi-address
Two Ethernet interfaces use different IP addresses and work separately in LAN1 and LAN2. One of them could be chosen as default LAN to transmit data.
Load Balance
Two Ethernet interfaces use the same IP address. And they share the bandwidth of the system, which is aimed at increasing the throughput.
Net Fault-tolerance
Two Ethernet interfaces use the same IP address. One is main, and the other is for backup. If the main Ethernet interface is damaged, it will switch over to the backup one automatically to ensure normal function.
