Note
In the load balance mode for Assigned Routing, the first WAN port (WAN1) will be saved for the
traffic of the IP addresses or the application service ports that are not assigned to other WANs
(WAN2, WAN3, and WAN4). Therefore, in this mode, we recommend assigning one of the
connections to the first WAN. When other WANs (WAN2, WAN3, or WAN4) are broken and
connection error remove (Remove the Connection) has been selected for the connection detection
system, traffic will be shifted to the first WAN (WAN1). In addition, if the first WAN (WAN1) is
broken, the traffic will be shifted to other WANs in turn. For example, the traffic will be shifted to
WAN2 first; if WAN2 is broken too, the traffic will be shifted to WAN3, and so on.
6.2.3 Protocol Binding
WAN Setting
The VPN Router allows maximum four WAN interface, the bandwidth and real connection of every WAN will
impact the load balance mechanism; therefore you need to set the Bandwidth and the Network service
detection by each WAN Port correctly. In “Interface Configuration”, click “Edit” to enter the WAN port
configuration.
Bandwidth Management
When Auto Load Balance mode is selected, the WAN bandwidth will automatically allocate connections
through sessions or IP to achieve load balancing for external connections. The network bandwidth is set by
what users input for it. For example, if the upload bandwidth of both WANs is 512Kbit/sec, the automatic load
ratio will be 1:1; if one of the upload bandwidths is 1024Kbit/sec, while the other is 512Kbit/sec, the automatic
load ratio will be 2:1. Therefore, to ensure that the device can balance the actual network load, please input
real upload and download bandwidths.
