    Default WAN Balancer Problem with DNS

    Good day. I would like to ask for your assistance regarding wan balancer..

    My goal is to balance my bandwidth between Igate (Wan A) and Balance (Wan B).

    Under Wan Balancer, I already set the traffic between the 2 Wans to 50%, Kindly see the attachments for my rules.

    I can see on my wan balancer sessions that both Wans have number of sessions..

    My problem is that I can't browse (continuous loading) when my wan balancer is enabled. I get the alert "DNS connectivity failed: DNS Server IP" My dns server is 8.8.8.8 4.2.2.2 on both Wans. I already tried using 8.8.8.8 8.8.4.4.

    Kindly help. Thanks!

    Does one of your WANs block DNS traffic to public DNS servers?
    If so you will need to add a route (not route rule) for traffic going to 8.8.8.8 to go to the gateway of the WAN that actually passes that traffic.

    I was going to say that looks like one of your WANs can't use Google DNS for some reason.

    I used dns 8.8.8.8 4.2.2.2 on my iGate (wan balancer disable) and it works. Maybe it's my Balance Wan which can't use dns?

    My iGate works fine with the dns 8.8.8.8 4.2.2.2 (Wan Balancer disabled). By adding route, you mean in the Configuration > Network > Routes of Untangle?

    WAN Balancer doesn't do anything with DNS. Untangle does, based on the configuration of the WAN interfaces in question.

    If you force all traffic to specific name servers out a specific WAN, and that connection fails those DNS servers won't be usable anymore. That sounds like a good way to have a broken network when the connection faults negating the advantage of dual wan.

    What does your iGate have to do with your ISP passing DNS to public servers?
    Yes.

    I already did some tweaks, I'll just monitor if it's effective or not.

    Thanks for the ideas!

    Hello there. I'm back..

    I tried using my ISP DNS on my Balance WAN and it worked. But after a while. It failed again.

    What failed? We need details as in network diagram, settings, what tests were done and their results.
