Muti-WAN

1 Muti-WAN

Muti-WAN enables you to set load balancing and advanced routing when you have multiple WAN interfaces. This module has no use if you only have one WAN interface.

2 Solution

You need to define line solutions at first. For example:

• "WAN1 Only": set WAN1 as a dedicated line for business servers only.
• "WAN2 & WAN3 Balanced": for office users to share these two lines.
• "WAN3 Only": traffic to certain websites will be in this line.

You can add multiple line solutions, for each solution, you need to define the load balancing rank for every interface.

3 Policy

A solution won't work without policy. Policy is the rule to define which traffic picks which solution. Settings:

• Source: source ip address or ip range. You can define IP as "Any", "Single IP" or "IP Range".
  • For "Single IP", a single ip or subnet is allowed(for example: 192.168.1.10 or 192.168.1.0/24).
  • For "IP Range", you need to input an ip range.
• Target, target ip or domain
  • For "Single IP" and "IP Range", the synax is the same as "Source".
  • For "Customize", you can select traffic by "application type", "web categories", "countries and regions" or "custom IP or domains".
• Ports: target ports to be applied.

Please notice: Rules are always processed from the top of a list down, first match wins. You may drag the re-order icon to re-order rules.

4 WAN Failover

"WAN Failover" feature detects line availability, in case one line fails, interface load will be re-balanced.

• "WAN Failover" is disabled by default.
• If "reconnect" is enabled, WAN interfaces will be automatically restarted on failure.
• For "static ip" WAN interface, NGF will automatically ping WAN gateway to check.
• Use IP addresses for connection testing is recommended.
