Question

SDWAN tuning

We have a Fortigate 200E with fw 6.2.9 and we have 4 wan circuits under SDWAN.  We also have about 200 clients that use SDWAN.  We see many web apps that complain about IP switching (thinking IP is hijacked).  We have used some SDWAN rules to force the use of only 1 link, but that defeats multilink reliability.  We would like to tune SDWAN such that a specific client continues to use the same WAN link for the whole day, or at least 8 hours, assuming the link has a basic level of quality. 

Does anyone know if this is possible or another way to accomplish this?

Thanks,

Dale Sykora

    Hi,

     

    SDWAN has 4 implicit methods of load balancing one of which is source-ip-based. The below link explains in brief regarding the same.

    https://docs.fortinet.com/document/fortigate/6.2.13/cookbook/683285/selecting-the-implicit-sd-wan-algorithm

    Have you tried using the source-ip-based method already?

    The algorithms are not time-based, so we cannot set this based on a day or for a few hours time period.
