In this section, we will continue from the last section and see how to get started with route table.
- Next, we are going to create a route table. A route table is basically a list of IP address ranges. And, this will tell Microsoft azure how to send traffic which is coming over your network. Hence, let’s search for the same in all services.
- It will take me to the below page.
- Let’s create a new route table.
- Upon creation, I can navigate in to the route table.
- Now, I can go into routes as shown below.
- Let’s add one. Now, let’s say, we want to implement a rule that says any traffic which originates from a server running on the backend, we want it go firewall before it leaves the network.
- Here, I have also copied the backend network address.
- And, we want this traffic to be sent to virtual appliance which is nothing but the hop type.
- And, this virtual appliance endup being a firewall, which we haven’t created. But, let’s say there is a firewall sitting at some IP say 22.214.171.124. Therefore, traffic originating from backend source will be sent to firewall.
- We haven’t associated this route table with our subnet yet. Therefore, let’s go to subnet section and say associate.
- I have chosen the virtual network, which I have created and associated with backend subnet. So, the traffic that travels over the backend subnet has to follow this route table.
Thanks for joining me. Stay tuned till next update.
