Just wanted to let the world know of an incompatibility between D-Link
Routers and the TFTP protocol.

I have a CISCO IP phone network with a remote TFTP server on UDP port
69 which D-Link would not allow through properly. Apparently port 69 is
reserved on D-Links for firmware or something else. So if you have
everything wide open and think your TFTP isn't setup properly it's
probably the D-Link.

I bought a Linksys and it worked no problem.

I wasted three damn days on this. I wouldn't wish my worst enemy the
same.
