LAN hosts (that is, the hosts that have not been assigned a preferential channel) to
process. On the Device, you can assign different preferential channel for different LAN
hosts.
8.3.2.3 Allocating Traffic according to Connection Bandwidth
On the Device, you can designate the ratio of traffic that will be allocated to each Internet
connection in advance. You can achieve this by specifying the Internet connection¶s
Weight, the connection that has larger Weight will take more traffic than the connection
that has smaller Weight.
In most cases, to properly allocate traffic, you may specify each
connection¶V Weight according to the ratio of each connection¶s bandwidth.

Weight.
Besides, when you have designated preferential channels for some LAN hosts, if you
specify each
connection¶V Weight according to the ratio of each connection¶s bandwidth, the
ratio of each connection¶s actual traffic and the ratio of each connection¶s bandwidth may be
quite different. In this case, you can adjust each connection¶s Weight according to the actual
situation.
8.3.2.4 Two Load Balancing Policies
Note
In this section, those hosts that have not been assigned a preferential NAT rule are
called
free LAN hosts
.
The
Load Balancing Policy
is used to control and balance the traffic among multiple
Internet connections. Note that the load balancing policy only acts on the free LAN hosts.
The
Load Balancing Policy
is configured in the
Basic > Load Balancing > Global
Settings
page, and the Device provides two load balancing policies: load balancing based
on IP address and NAT session. Their implementation mechanisms are as follows.
1. Load Balancing Based on IP Address
Note that here we assume that each LAN host only has one IP address.
If you choose IP address as the load balancing policy, the Device will assign the free LAN
hosts¶ IP addresses to each EasyIP NAT rule in turn. The ratio of the numbers of the IP
addresses assigned to each EasyIP NAT rule is the same with the ratio of each rule¶s
