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

Use another host as hop to unreachable network

route all SSH connections to 2.2.2.2(unreachable by sonicwall) via 1.1.1.1 (reachable)

1. create Network > address objects, create 2.2.2.2 and 1.1.1.1 addr objects

2. click on Network > routing > add route
