Posted on by — No Comments ↓

Welcome back everyone, today we will be taking a look on how to update a virtual Network. yes, a virtual Netwoik can be updated!

So imagine You’re assisting an Azure Admin with specific resource tasks.
A new Linux VM is needed for an FTP server, while the current VM is underutilized.
To monitor network flow and usage, the admin requests a new subnet for the FTP server.
The existing subnet must remain unchanged for future VM deployments. So we need to create a new Subnet for our work.

** First we create a new subnet on an existing virtual network (vNet)**

  • search and select virtual machine

search and select virtual machine

select

  • create subnet

create subnet

  • give name and add

give name and add

You have successfully finished creating a subnet. Only SFTP traffic will be sent over this subnet. You must set up a network security group to limit which ports on the subnet are permitted in order to improve security

  • select virtual Network

select virtual Network

create

  • give group name

give group name

create

go to resource

Now we create an inbound security rule

create and

  • change name
    change name

Congratulations! You’ve set up rules to permit incoming FTP traffic and established a new network security group. The new network security group must now be linked to the ftpSubnet

select

  • select the subnet we created earlier and save

select the subnet we created earlier and save

  • Well done. You appear to have finished the necessary steps to get the network ready for moving the existing Linux virtual machine to a new subnet that is intended to manage incoming FTP traffic.
