Hello @Rajesh Swarnkar ,

Welcome to Microsoft Q&A Platform. Thank you for reaching out & hope you are doing well.

I understand that you have some basic queries related to Azure Route Table and Azure NSGs. I have provided the answers below:

NSG can be associated with what kind of resources?

Network security group (NSG) can be associated to any virtual network subnet and/or network interface in a virtual machine.

Refer: https://learn.microsoft.com/en-us/azure/virtual-network/network-security-group-how-it-works

https://learn.microsoft.com/en-us/azure/virtual-network/manage-network-security-group?tabs=network-security-group-portal#change-a-network-security-group

https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-faq#what-would-be-the-behavior-when-i-apply-both-nsg-and-udr-at-subnet

Route Tables can be associated with what kind of resources?

Route tables can be associated to Virtual network subnets.

Refer: https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-udr-overview#user-defined

https://learn.microsoft.com/en-us/azure/virtual-network/virtual-networks-faq#can-i-specify-custom-routing-policies-on-my-vnets-and-subnets

https://learn.microsoft.com/en-us/azure/virtual-network/manage-route-table#associate-a-route-table-to-a-subnet

Do NSG and Route tables have any pricing?

No, there are no additional charges for creating NSGs and route tables in Microsoft Azure.

Answer 2

Hello @Rajesh Swarnkar

Network Security Groups (NSGs) can only be associated with

• Virtual Network Subnet
• Virtual Network interface

https://learn.microsoft.com/en-us/azure/virtual-network/network-security-group-how-it-works

Route Tables can only be associated with Virtual Network Subnets

[https://learn.microsoft.com/en-us/azure/virtual-network/manage-route-table#associate-a-route-table-to-a-subnet

Network Security Groups and Route tables do not cost to use. Any cost here relates to Virtual networking pricing, Network watcher (if using Traffic Analytics for NSG's) or any diagnostics logs exported for NSG's (though this will be listed as an Azure Monitor, Event hub or Storage account cost as this is where the data will be ingested)

I hope this helps provide you with the information you need. If it does, please make sure to mark the question as answered so it helps other people in future.

Kind regards

Alistair
