IP rejected by DNS on Netgear N600 WNDR3400v3
I have a website and use CORE FTP to upload files to the DNS. I have used the Netgear router and CORE FTP for years with not problem at all. Yesterday I attempted to connect to the DNS to upload fi...
Why does Core Ftp work when the desk top is plugged directly into the ISP modem but is rejected by the DNS when the desk top is plugged directly into the Netgear router?
You say contact the DNS and have them correct the problem. Would you think they have someone sitting in their database monitoring if my connection is directly from the desk top computer or the connection is from the Netgear router so they can deny a connection if it is from the Netgear router?

I don't know. This is the first I've heard about that behavior. I
know nothing about your (unspecified) "the ISP modem". I've never seen
a complete IP address for any part of your system.
> You say contact the DNS [...]
I never said that. I'm still not sure what "the DNS" means to you.

No, but I'd expect them to be able to see your external/public IP
address, which is more than _I_ can do unassisted. I can _imagine_ that
your ISP gives your computer and your router different IP addresses when
they're connected to your (unspecified) "the ISP modem", which could
explain that behavior.
As already explained, I _would_ expect any blacklist involved here to
be maintained by your site-hosting organization, not by your ISP (who
agreed), and not by your router (which could not generate a message like
that, as I imagine it, anyway).
> You "got the error message" from this "CORE FTP" program, or what?
Still a mystery. I've never seen that actual message in context,
either. I'd guess that it comes from the FTP server, and gets passed
along by your FTP client program, but these are guesses based on
incomplete information.
Knowing nothing, I'd guess that a message like "No connections
allowed from your IP [address]" was related to the IP address seen by
the system which is rejecting the connection, so I'd be looking at that
address in the two different situations to see if it might differ.
Blame Assignment is Job One. You seem intent on blaming your router
(or your ISP) for things which they can't (so far as I can see) be
responsible. I'm always open to actual evidence, but only one of us has
access to any of the relevant information, and he has been pretty stingy
with it up to now. ("got the error message", "my IP address
69.2X.XXX.X", for example.)
_If_ your ISP gives your computer and your router different IP
addresses, then you might be able to induce it to give your _router_ a
different (WAN/Internet, external/public) IP address by changing its MAC
address (on that interface).
Visit http://netgear.com/support , put in your model number, and look
for Documentation. Get the User Manual (at least). Read. Look for
[BASIC > Internet >] "Router MAC Address".
But, if your site-hosting organization had some reason for
blacklisting your old IP address, then I wouldn't bet on a new one being
more than a temporary work-around.
