I have two network.

Network 1 on interface X0 and network 2 on X7.

I need network 1 to use WAN on interface X1 and network 2 use WAN on interface X8.

All you really need to do is create a route that directs traffic from X1 to X8.

Go to Network -> Routing

then select Add

Source would be what you named the lan behind X1
Destination would be Any
Service would be Any
Gateway would be Secondary Default Gateway
Interface would be X8

That should do it.

Are you sure you have it configured correctly.

The source must be the lan behind X1 and NOT the X1 interface.

Have you defined the Seconday Default Gateway to be the first hop (ISP router?) after the interface and NOT the X8 interface ip?

The secondary default gateway should have been auto added when the interface was defined.

This assumes you have a recent model Sonicwall with a recent version of SonicOS.

Does the Secondary Default Gateway point to an ip that is on the same subnet as the X7 ip?

not sure this is related but you are using wrong subnet masks for X3 and X8

10.0.0.0/255.0.0.0 is meaningful
10.10.0.0/255.255.0.0 and quite a few others are ok but the one you are using is not

What interface is the wireless connected to?
can i see the routing table before you add the rule ?
can you confirm both WAN connections work properly ?

What model Sonicwall do you have and what is the version of SonicOS Enhanced. The definition and how the Secondary Default Gateway is created has changed at version 5.5.

Did you make sure your NAT rules were laid out properly? That is most likely the cause of your issues...
