Configure a Route Table using the Azure Portal

This Configure a Route Table using the Azure Portal lab provides learners with an understanding of the broader Azure portal ecosystem. Learners are introduced to a vital concept, such as how to route traffic through Azure Firewall, which is crucial for a forensics Analyst or a System Administrator.

Challenge Overview

In this lab, you will simulate real-world scenarios. For example, If you are working as a system administrator in a company. Your job is to deploy virtual networks for Azure workloads. You need to assure that traffic is routed through an Azure Firewall. In this challenge, you will accomplish the following things:

Create a routing table to manage the traffic for Azure Firewall

By default, Azure routes traffic between all subnets. You can build your routes to reverse Azure's routing. The knowledge to build system routes is important if, for instance, you need to route traffic between subnets within a virtual network appliance. In this step, users will:

• Create a route table: For the Azure Portal Menu.
• After that, Create a route by using Azure Dashboard.
• Create a virtual network with multiple subnets.
• Associate a route table to a subnet.
• Route traffic from one subnet to another.

After this,

Users will create an Azure Firewall in a pre-configured virtual network

Managing outbound network access is an essential component of an overall network security strategy. For instance, you may want to restrict access to web sites. Or, you may need to restrict the outbound IP addresses and ports that can be obtained. In this step, users will learn how to:

• Set up a test network environment.
• Deploy a firewall.
• Create a default route.
• Test the firewall.

Finally, users will create a user-defined route to route the subnet resources so they can use the Azure Firewall. Microsoft Azure Virtual Networks allows users to handle the movement of cloud-based network traffic. One example of custom Route Tables is to route all network traffic through a Virtual App that is accountable for ensuring network traffic defense.

Azure has various pre-defined system routes. These pre-defined system routes control traffic between the internet, on-premises devices, and other Azure devices. After completing this hands-on-lab, you will learn how Azure system routes are used and configured.

Who Should Take this Configure a Route Table using the Azure Portal Lab?

This lab is perfect for anyone who is looking to earn expertise in configuring a Route Table and who wishes to perform Microsoft Azure related tasks within the company. Additionally, experts in the following positions will find this lab helpful:

• Enterprise Architects
• Network Operations Specialists
• System Administrators
• Network administrators
• Server administrators

What Does the Configure a Route Table using the Azure Portal Lab Include?

The Configure A Route Table Using Azure Portal Guided Lab demands students to build a routing table and firewall for a virtual network. After completing this lab, students will learn how to build route tables, firewalls, and add a route using the Azure portal. This lab needs to be launched in its window, and it takes 30 minutes to complete. After completing the tasks, students can come back again to continue.

Azure Route Tables enable users to create network routes so that the firewall can manage the traffic between subnets and the Internet. For the network interfaces to be authorized to collect and deliver traffic, knowledge of IP forwarding is essential. Microsoft Azure Virtual Networks allows users to handle the movement of cloud-based network traffic. One example of custom Route Tables is to route all network traffic through a Virtual App that is accountable for ensuring network traffic defense.

What is a route table?

The routing table, also known as RIB (Routing Information Base) is a data table saved in a router or a web host. The router or host records the routes to special network addresses with routes. The routing table includes data about the topology of the network. All IP-based devices, routers, and switches use routing tables.

For example, Routers analyze the target IP address of a collected packet and execute routing protocols, respectively. To discover which interface the packet will be transferred, routers utilize routing tables. A routing table records all networks for which routes are identified. Each router's routing table is different and saved in the RAM of the computer.

When a router gets a packet that requires to be sent to a host on a different network, it checks its target IP address and scans the routing data collected in the routing table. Each record in the routing table contains:

• The network and the subnet mask.
• The remote router.
• The outgoing interface.
