SD-WAN and interface preference

  • 1.  SD-WAN and interface preference

    Posted 12 days ago
    Hi,

    I am using sd-wan and until now I did not have problem with it. I did an upgrade yesterday to version 6.4.5 and now I am facing some problem. Some system which are reachable on the internet are not answering because I think we are going out with wrong public IP address. We are using volume alogorithm and of cource the sd-wan itself will distribute even the traffic and thats why we are facing this issue, however I dont know why this issue were not present before.

    Can I solve this issue by creating a sdwan rule with interface preference? Is it the only thing I need to do, or should I do something else beside sd-wan rule?

    I have run into this same issue. What i have done to solve it is create an SDWAN rule. Create an FQDN address object to the url and in the SDWAN rule specify traffic going out to that object to use a specific wan interface of the SDWAN interface. That way no matter what it will always appear as the same IP address from the FQDN you are accessing.

    here are some screenshot examples
    this is the FQDN address for gmail ( mail.google.com ) as an example


    The rule would be source : all or whatever else would apply in your scenario with destination the created address object using manual outgoing interface and select which to use
