What is azure NAT gateway?
NAT gateway resources are part of Virtual Network NAT and provide outbound Internet connectivity for one or more subnets of a virtual network. … NAT provides source network address translation (SNAT) for a subnet. NAT gateway resources specify which static IP addresses virtual machines use when creating outbound flows.

How is Azure firewall different from network security groups?
What is the difference between Network Security Groups (NSGs) and Azure Firewall? … Together, they provide better “defense-in-depth” network security. Network security groups provide distributed network layer traffic filtering to limit traffic to resources within virtual networks in each subscription.
Is Azure firewall Layer 7?
There is no shortage of firewall options in Azure for network security at the transport (Layer-4) and application (Layer-7) layers of the network stack. … Azure Web Application Firewall (WAF): An extra add-on for the web application gateway (WAG) to protect HTTP/S traffic at Layer-7.
