Internet Failover

    Does anyone use an Internet Failover system, for internet continuity when your primary service provider's connection goes down?  If so, I would love to hear what solutions you have tried.  We have had terrible, "in and out" internet service over the past two weeks and need a backup plan...

    Hi Frank.  We have a SonicWall Firewall in place that accommodates load balancing and failover activity in the event of an outage.  It also allows for traffic Round Robin or Spill-over features.  Most firewalls have these features in place and simply need to be configured.  Having two public interfaces is a requirement prior to enabling.

    As an aside, make sure your two providers take separate physical paths along the easement to enter your building.  It does no good to have redundant providers in the same conduit getting severed at the same time.

    In our permanent offices and/or large job sites where we need to keep the internet circuits up, we have 2 different circuits by 2 different carriers coming in on 2 different wires to provide redundancy.  Hopefully an outage would not affect both carriers.  In some cases we have a wireless cradlepoint connected as the secondary provider.  We use our firewall to control the failover when the primary carrier goes down.  Over the years we have had firewalls that would not automatically fail back to the primary when it came back up and we would have to do that manually where with other fire walls they would automatically fail back when the primary carrier came back up.


    You can discuss this with your tech support people and they can verify your firewall settings are able to do this, or you may need to upgrade your firewall to get this capability.


    If you would like to discuss, I would be glad to talk to you about what we are doing.  Hope this helps.

    In addition to our dedicated AT&T fiber we also have what I guess you would call "business dsl" from Comcast.  The download speed is the same (50mbps) but, like most DSL, the upload is appx 1/10 the download.  It is a fairly inexpensive back-up at $199/mo and also helps as an alternative path when the load on the primary fiber is too heavy.

    Hi Frank,

    We also use Sonic Walls, but we have ATT fiber line as our primary and Cox as our secondary ISP.
