Explanation:
To ensure that all traffic to the internet from subnet3-1 is forwarded to the appliance in subnet3-2 for packet inspection, you can use User-Defined Routes (UDRs) to direct the traffic. Here's how you can do it:
* Navigate to the Azure Portal.
* Search for "Route tables" and select it.
* Click on "Create".
* Enter the following details:
* Subscription: Select your subscription.
* Resource Group: Select an existing resource group or create a new one.
* Name: Enter a name for the route table (e.g., RouteTable-Subnet3-1).
* Region: Select the region where your virtual network is located.
* Click on "Review + create" and then "Create".
* Navigate to the newly created route table.
* Select "Routes" from the left-hand menu.
* Click on "Add" to create a new route.
* Enter the following details:
* Route name: Enter a name for the route (e.g., RouteToAppliance).
* Address prefix: Enter 0.0.0.0/0 to route all internet traffic.
* Next hop type: Select Virtual appliance.
* Next hop address: Enter the IP address of the appliance (10.3.2.100).
* Click on "OK" to add the route.
* Navigate to the route table.
* Select "Subnets" from the left-hand menu.
* Click on "Associate".
* Select the virtual network that contains subnet3-1.
* Select subnet3-1 from the list of subnets.
* Click on "OK".
* User-Defined Routes (UDRs): These allow you to control the routing of traffic within your virtual network. By defining a route that directs all internet-bound traffic to the appliance, you ensure that the traffic is inspected before it reaches the internet1.
* Virtual Appliance: This is a network appliance that performs specific functions, such as packet inspection, and is treated as a next hop in the routing table2.
* Route Table Association: Associating the route table with subnet3-1 ensures that all traffic from this subnet follows the defined routes.
