TFTP for WLC not working

[tarmahmood1]

I am trying to setup a TFTP server in Azure VM and download the image from WLC. TFTP is pingable but when i intiate the downloading from WLC it says it is not reachable. In between i have Meraki MX68 FW and i have allowed all traffic. Diagram attached of setup. Any suggestion.

Hi

  It seems communication problem. Ping does not means that the communication is happening. What you can do for testing is try FTP instead because FTP is based in TCP so you can test before use with telnet command.

From you machine you can issue ' ftp Azure VM : 21' if the connection open, you know you are good.

Hi,

Thank you for reply. I am wondering if 1850 works with FTP, since i am only getting TFTP option. Also i tried CLI it shows FTP mode but later when i execute Transfer download start, it shows TFTP in summary table before executing the tftp session attached screenshot. Do you think still i need to try FTP Azure VM:21 option. Thanks

I was actually thinking in a different device. This could be done on your machine. If windows machine you need to enable telnet first and then test with telnet vm-cloud 21.

  My idea was to ensure sure that the communication is OK between you and cloud as you mentioned that the transfer failed.

TFTP worked as in VM(windows) i added rule in windows FW to allow port 69 and application(mycase TFTP64.exe).
