WAN LINK LOAD BALANCE x WAN LINK MANAGER

Fernando Dias1

Hi,

 

I have 2 WAN links and I created a firewall rule where the "Primary Gateway" has been defined as "WAN Link Load Balance", however, in Configure->Network->WAN Link Manager the settings are 1 wan link as active and the other backup.

 

In this scenario, when the firewall rule would be matched, how the routing would work? 

 

Thanks in advance,

 

Fernando Dias

    It depends on what you configured in the WAN Link Manager. By default a second uplink interface will become another "Active" interface. If you change it to backup there are 2 options below.

    "Activate This Gateway" by default stays on "Manually" -> In this case if WAN1 goes down nothing happens automatically and you have to activate the backup line manually.
    When you select the other option "If ANY (I would recommend this) Active gateway fails" WAN2 automatically goes up when WAN1's failure conditon occurs (by default it tries to ping its default gateway but you can change this to any IP you like).

    Hi,

     

    I appreciated your comment.

    But back to my scenario if the firewall rule is set to Load Balance and wan link manager is set to Active/Backup, when the firewall rule matched, the firewall would obey the firewall rule or the wan link manager?

    "WAN Link load balance" means "use the gateway like configured in the WAN Link Manager".

    If you have 1 active and 1 backup/standby WAN uplink it means that the whole traffic is routed via the active uplink and only over the backup, when the active one fails. The firewall rule will match in both cases.
