Two Internet connections, Two network segments, bur different default routes.

Joseph909

I have a TZ670 appliance. Internet provider 1 is connected to X1. Internet provider 2 is connected to X2. There are two LAN segments X0 and X3. What I want to accomplish is for all Internet traffic originating on X0 to route to X1 and if X1 is down fall back to X2. At the same time I want Internet traffic originating on X3 to route to X2 and fall back to X1. Any help would be greatly appreciated.

X0 --> X1 then X2

X3 --> X2 then X1

Hello @Joseph909,

Welcome to SonicWall community.

You can use the following configuration,

1) Enable WAN Load balancing and use X1 as primary and X2 is secondary with basic failover mode

2) Create a static route to send outgoing traffic from X3 subnet to exit on X2

Please make sure you set logical probing on both the interfaces so that we can determine the internet connectivity status from either interfaces.

Result:

1) X0 exits out of X1 as that is the primary connection and if that interface fails, falls back to X2 as that is the secondary connection on WLB group

2) X3 exits out of X2 due to static routing and uses X1 if the X2 fails probing on WLB disabling the static route.

Thanks!

I was so used to the old interface I missed the +Add at the bottom of the screen. I was able to add the route and everything is working now.

Thank you.
