Load Balancing - Symantec 360R - Security Gateway SGS Administration Manual

Load balancing

Table 3-4 High availability modes
Mode Description
Backup WAN port only passes traffic if the other WAN port is not
functioning.
By default, WAN1 is set to Normal and WAN2 is set to Off.
Bandwidth aggregation lets you combine the amount of traffic that goes over
WAN1 and WAN2 to increase the amount of bandwidth your clients can use. For
WAN data transfer, data aggregation can provide up to double the WAN
throughput, depending on traffic characteristics.

See "Main Setup tab field descriptions"
1 In the SGMI, in the left pane, click WAN/ISP.
2 On the Main Setup tab, do the following:

■
mode.
To configure the WAN2 port, under WAN2, select a high availability
■
mode.
3 Click Save.
Symantec Gateway Security 300 Series model 360 and 360R appliances each
have two WAN ports. On these appliances, you can configure high availability
and load balancing (HA/LB) between the two WAN ports.
You can set the percentage of packets that is sent over WAN1 or WAN2. You
enter a percentage only for WAN1; the remainder of the packets are then sent
over WAN2. If you have a slower connection, use a lower value for that WAN
port for best performance.

1 In the SGMI, in the left pane, click WAN/ISP.
