Azure Route table and using it in Azure Firewall
- Azure routes the subnet traffic by default which allows the communication to the internet from subnets and communication b/w subnets
- Azure allows us to create the custom route tables in which we define the next hop for our traffic
- Lets create a network
- Now lets create Azure firewall
- After the firewall is created lets create a route table
- Lets associate route table to web, app and db subnets
- Now lets create a route in the route which redirects all the traffic from the subnets web, app, db outbount to firewall
- Enable DNS Proxy
- Create an IP Group for specifying the ip ranges at one place
- Now lets enable the Diagnostic Settings in Azure firewall
- Exercise: Create a vm in the web subnet with public ip and then login into vm and try to ping google.com and yahoo.com
- google.com should be pinged and yahoo.com should be failed
