Hello team!!

 

I need to do the following but I dont know how.

We have the only 2 WAN connections in the same SD-WAN

Everything is working fine, but now we need to specific IP range to use WAN2, and when WAN2 is down, this specific IP range should not use WAN1 connection (Should not navigate).

Is this possible to accomplish this with SD-WAN rules?

 

Thanks in advance.

Regards,

Damián

Hi damianhlozano,

 

Yes, it is possible.

You need to use the SDWAN rule manual method to route traffic for certain sources via specific wan interface and can setup perf. sla when it is down it will remove the route via that specific interface

    Thank you sjoshi for your response!

    I still do not see how to accomplish this.

    I think if I create a rule with manual method, to this specific IP range, to use WAN2, when WAN2 is down, this specific IP range should use the implicit rule, is this correct?

     

    Also, it does not matter, but once a Fortinet engineer told me that SLA are just considered in those rules with an "Interface selection strategy" capable to consider WAN SLAs, for example "Lowers Cost (SLA)", this engineer told me that SLA values are not considered on manual rules.

     

    Thanks in advance.

    once the perf sla is down it will remove the route from wan2..now the manual rule itself wont get trigger and will look the below rule
