FTP server is not accessable

Question

Hello Concern,

I have configured FTP server in Azure portal. I can access the FTP server real IP from any Microsoft Azure VM but I am unable to access the FTP server from outside network. Is there any restriction from Microsoft site?

Link: ftp://168.63.244.60/
IP: 168.63.244.60

Thanks,
Shamiul

Answer 1

The NSG associated to a subnet is not required/mandatory. It's not a problem if there isn't any NSG on the subnet.

This is a how-to "how to configure FTP Server on an Azure Windows VM". Maybe you could verify the step-by step how-to with your configuration.

Answer 2

The FTP Server service is running on a Linux or Windows Server VM?

To access the FTP Server service on a Azure VM you need:

• You need to allow incoming FTP traffic on the OS firewall.
• You need to allow inbound FTP traffic on the Network Security Group (NSG) associated with the Azure VM
• You need to allow inbound traffic on the Network Security Group (NSG) associated with the Virtual Network/Subnet of the Azure VM

Answer 3

In the Azure portal navigate to the VM and select Networking.
There you can see the NIC and all associated NSGs (directly to the VM and to the subnet of the VM if there is any):

Also you can run the Connection troubleshoot. The first screenshot shows a "positive" the second screenshot shows a "negative" with details what is blocking (i don't have a FTP Server installed on my VM01 and no NSG inbound rule is defined for FTP).

Hope this helps.
