    I rarely use Linux but now, for one reason, I have to, because I have a problem with my provider.

    I use the Cisco IP Phone 7911 in the company. The address of the remote TFTP server is My CISCO phone can not establish a connection because, I suppose, the provider blocked ports or services at my address.

    For connection to a remote TFTP server we use the Mikrotik router. I would like to use the tcpdump command to get a response, where there is a problem in the path to my TFTP server.
    Can you help me?
