Route Google services through a second internet connection

scenario: I have 2 internet connections connected to SW,

Fiber(X1) - Fiber provider A
Coax(X2) - Coax copper cable provider B

Fiber is having issues reaching Google/Gmail/etc

I will route anything bound to Google via 2nd Coax connection

1. check whats the interface for Coax (X2)
   
   

2. create Address objects for google (nslookup mail.google.com, nslookup calendar.google.com, nslookup www.google.com) - create a Address Group w these address objects
   New Address Object (IPV4)
   WAN, Network, 142.251.167.0/255.255.255.0 etc etc
   
   create new Address Group "Google IPs Group"
   
   

3. create a new Route rule
   Name: Google via Coax
   Source: Any
   Destination: "Google  IPs Group"
   Service: Any (standard route)
   Interface: X2
   Gateway: X2 Default Gateway
   Metric: 1
   Comment: Temporary google via Coax
   disable route when interface is connected
   
   

4. Create NAT rules to translate source and dest IPs
   
   1. NAT Policies > Add
   Name: "From Google"
   Original Source: "Google IP Group"
   Translated Src: Original
   Original Dest: Any
   Translated Dest: Original
   Original Svc: Any
   Translated Svc: Origin
   Inbound Interface: X2
   Outbound Interface: X2
   IPV4 only
   enable NAT policy
   
   2. NAT Policies > Add
   Name: "To Google"
   Original Src: Any
   Translated Src: Original
   Original Dest: "Google IP Group"
   Translated Dest: Original
   Original Svc: Any
   Translated Svc: Original
   Inbound Interface: X2
   Outbound Interface: X2
   Comment: To Google, IPV4 only, enable NAT policy

packets outbound to Google services will flow over Coax connection (X2) and be masqueraded by Sonicwall
