Re: wtf mate

TFTP (port 69) is used to provision and provide firmware upgrades to the VoIP endpoint (analog phone adapter). TFTP is giving way to HTTP and HTTPS as the preferred method (by service providers) to manage VoIP end points. These protocols tend to work much better when a home or office network is supporting the VoIP endpoint connected to the LAN. CNET readers would have been better served if this information was included.

Re: wtf mate

Also some network devices (cablemodems perhaps?) TFTP their configuration files from a server. Usually that would be the device using a dst UDP port of 69 (and something else for the src, meaning the dst UDP port for the server->dev traffic), but still...UDP port 69??? jeesh. What a screwup, AT&T.

Twentynine Palms, CA		 I just spoke with a Vonage tech and was told that Vonage has a workaround for this issue. I just had my firmware upgraded, even though I use Adelphia Powerlink (one of the ISPs blocking port 69).
