6.2 Multi- WAN Setting
6.2.1 Load Balance Mode
Auto Load Balance Mode
When Auto Load Balance mode is selected, the device will use sessions or IP and the WAN bandwidth
automatically allocate connections 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.
Item Description
Session Balance
If “By Session” is selected, the WAN bandwidth will automatically allocate
connections based on session number to achieve network load balance.
IP Session Balance If “By IP” is selected, the WAN bandwidth will automatically allocate
connections based on IP amount to achieve network load balance.
"
Note
For either session balancing or IP connection balancing, collocation with Protocol Binding will
provide a more flexible application for bandwidth. Users can assign a specific Intranet IP to go
through a specific service provider for connection, or assign an IP for a specific destination to go
through the WAN users assign to connect with the Internet.
For example, if users want to assign IP 192.168.1.100 to go through WAN 1 when connecting with
the Internet, or assign all Intranet IP to go through WAN 2 when connecting with servers with port
80, or assign all Intranet IP to go through WAN 1 when connecting with IP 211.1.1.1, users can do
that by configuring “Protocol Binding”.
"
Attention
When the Auto Load Balance mode is collocated with Protocol Binding, only IP addresses or
servers that are configured in the connection rule will follow the rule for external connections;
those which are not configured in the rule will still follow the device Auto Load Balance system.
