|  Somebody Will Get a promotion
The idiot that told the project team to use port 69 will get a raise and probably get promoted to Vice-President of "something".
I am sure those on the project team who said udp 69 is a RFC standard are getting pink slips as we speak.
Isn't AT&T trying to "prove" to the business world they know "networking" and internet infrastructure?
Good job guys, how about for the next project try using this unknown port, tcp 21. Better yet lets use this port tcp 443 that nobody uses, cause it is really high up in the numbers.  |

Greenville, SC | You miss the point, like the poster above says they aren't using the port for anything unusual they are using TFTP to transfer config's and upgrade's. This is normal and ATT did nothing wrong by using it in this way. |

If they are using TFTP only for firmware upgrades then why the disruption of service? |

Victoria, BC | The port is being blocked due to a number of viruses and trojans that are setting up tftp servers on unprotected clients. |

They probably get their configs via TFTP so once someone power-cycles their VOIP adaptor they can't get a config. |

Sometimes the ISP will block things that it assumes to be safe to block. If something is going out of the ISP's network and onto the next teir 2 ISP or backbone and it has a source IP address that does not belong to the ISP and vice-versa, it will usually get blocked (this is spoofing). Any stray RFC1918 addresses get blocked too (like 192.168.100.3).
