Purpose: To change load balance mode or adjust interface weight.
Location: Gateways > (Selected Gateway) > SD-WAN > Rules > Edit Default SD-WAN Rule
When SD-WAN is enabled and saved, a default SD-WAN rule is created. The default SD-WAN rule can do load balance by source IP and destination IP, sessions or volume. No SLA can be configured in default rule. For default SD-WAN rule, weights of Session and Volume are in percentage. The sum of weights must be 100%.
The default SD-WAN rule is created when SD-WAN is enabled for the first time. It appears on the Gateways → (Selected Gateway) → SD-WAN → Rules page.

Procedure

  1. Under Load Balance Mode, select a mode used to do load balance traffic between WAN1 and WAN2 links.
    1. Select Source IP if you want to do traffic load balance based on source IP.
    2. Select Source IP and Destination IP if you want to do traffic load balance based on combination of source IP and destination IP.
    3. Select Session if you want to do load balance according to the session number's ratio. Configure the weight using percentage (the sum of the weights must be 100%).
    4. Select Volume if you want to do load balance according to the bandwidth ratio. Configure the weight using percentage for the volume (the sum of the weights must be 100%).
  2. Click Save.
