The Graveyard - Products No Longer Supported => Routers / COVR => DIR-655 => Topic started by: basboycjj on October 06, 2010, 06:51:28 AM

I installed my DIR-655 about a month ago. Since then, I have been unable to authenticate on an external ftp host that I have used for years. When I remove the router or go outside of my network it works fine. I am able to make a connection to the host. It will request my credentials. After I supply username and password, I get a Response of 530 Login incorrect.
I have modified every setting I could fine and reset the router to the factory defaults, but it doesn't help. Only when I remove the router can I log in.
Any ideas?
Thank you.

Hi basboycjj,
How are you connecting to the Internet, as you have not disclosed? Cable, FIOS, DSL?
Which FTP Server are you talking about?
What modem are you connecting the Router to?
-
I am in a cynical mood, so let's share that one with the board too: do people think crystal balls actually exist? ;)
Sorry, but it's close to obvious that a bit more info is really necessary to get something close to an answer
-
I am connecting to ftp.fatcow.com
Cable modem is an Arris TM502G
I'm happy to provide more information, but I don't know what else is really relevant. I'm not real confident anyone is going to have an answer, but I'm fishing. I am able to connect to the ftp but can't authenticate and the problem exists only with the router in place. Just weird.
-
Also I can successfully authenticate to other ftp servers

Hi basboycjj,
Two things to check when you have the problem with the Router in line.
1. - Make sure that the Router is showing your current IP Address from the Cable Modem. If not, Router may not be correctly sync'ed to the Cable Modem.
2. - Make sure that the Router has the correct Date and Time.

I just checked. Both of these are correct. Thank you for the thought.

Hi basboycjj,
Since fatcow, is a Paid Web-Hosting site, they may be using a different port then port 21. Find out what port they use and open that port up in the Router's Settings.
Or simply use http://192.168.0.1/Advanced/Web_Filter.shtml (http://192.168.0.1/Advanced/Web_Filter.shtml)
-
I have verified with them that they do use port 21 and that it is open

Hi basboycjj,
Are you having your Router's Logs being mailed to you?
Make a note of the date and time you try to contact, then Email the logs manually to you and see what the Router may be blocking.
-
Cleared logs, set to record all types of logging, attempted to log into ftp, authentication failed as has been the case, emailed logs to myself, nothing showing as blocked (just shows that I cleared the logs)
Thank you.
-
Are you using a web browser or FTP client?
-
I get the same result with a web brower, ftp client, or command line
-

If you can connect through the router to other FTP sites then the problem is with that particular FTP site not the router.
-
Maybe the FTP server has blocked your IP.
-
I am able to authenticate with the ftp site when I connect directly to my modem. So, that would be the same public facing IP address.
I have addressed this with the owners of the ftp site. They claim they don't see anything on their side.
It has to be something they are doing that doesn't like something the router is doing.
-
Based on your description of the problem, my WAGŪ is the back-connection of active mode transfers is being blocked. This is a VERY common problem for endpoints behind a router/firewall.
This would probably be easy to verify if you could see the logs from the FTP server. Assuming you can't do that, and you know the IP address of the site you're connecting to, try looking at the D-Link's logs and see if there are incoming connections being blocked. If you see any, or just want to try a possible solution anyway, look around your FTP program's settings for "passive mode" and make sure it is enabled.

Hi basboycjj,
Turn off the Router's Firewall and see what happens. I assume you have a Software Firewall being used?

I've tried both active and passive, but I don't even get that far since I can't authenticate. I don't have access to the server logs, but I have had them check and they said they don't see anything. My logs don't show any blocking either.
Thanks

There is no complete turn off for the firewall. I have added my computer to the DMZ and it didn't help. I have also adjusted the firewall settings (SPI and NAT Endpoint Filtering) and nothing there helped.
Thanks.
