How do I route all traffic to a SonicWall NSv using a different address space (different VNet)?

DESCRIPTION:

RESOLUTION:

1. Create a virtual machine which is using a  different address space (different resource group) and different subnet (10.0.4.4/24) and SonicWall NSv  X0 interface of SonicWall 10.5.1.4/24 and X1 interface of SonicWall 10.5.0.4/24.
   
   
   
2. Create a VNet peering between both the virtual network (SonicWall NSv) and (MACHINE_TEST_DIFF_VNET) under Virtual networks > AzureNSvSonicWall.
   
   
   Note: Please allow traffic from AzureNSvSonicWalltoMACHINE_TEST_DIFF_VNET to MACHINE_TEST_DIFF_VNETtoAzureNSvSonicWall and vice-versa.
   
   
3. Create a route table under Home > Route table > Create route table.
   
   
   
4. Add a route which will send any traffic to the next hop as 10.5.1.4 under Home > Route tables > MACHINE_TEST_DIFF_VNET_ROUTE_ALL.
   
   
   
5. Associate the subnet to the route table by selecting the virtual network that the NSv is a part of and subnet as 10.0.4.0/24.
   

NOTE: After configuring please create a route in the SonicWall to reach 10.0.4.0/24 subnet via X0 of SonicWall with gateway as 10.5.1.1.

The local virtual machine will not be accessed through the public IP so a NAT and access rule are required to access the virtual machine via WAN to LAN.
