Dual WAN
Dual WAN is specially designed to offer users failover/fallback.
Auto failover/failback is to ensure an always-on internet connection. Users can set a WAN1 (main
WAN) and WAN 2 (backup WAN), and when WAN1 fails, it will switch to WAN2, and when WAN1
restores, it will switch to WAN1 again.
Load balance provides optimal bandwidth sharing for multiple PCs on your network, or allows
maximum reliability with network redundancy. Load balance supported by BiPAC 7600NX(L) balance
network bandwidth for network traffic through two WAN connections, ideal for small-to-medium
business that requires increased bandwidth, network scalability, and resilience for mission-critical
network and internet applications.
