I hope somebody can help me to isolate a problem that I am experiencing.
I am on a MTN Data Contract. I use a MTN USB Modem to connect to the internet.
When I connect to the internet, MTN automatically assigns an IP address (Dynamic IP Address) to my computer/connection.
I use a variety of software applications to FTP files to servers in various locations around the world.
Most of the time depending on the IP address that MTN assigns to my computer/connection I am Not able to access my files via FTP. I am always able to connect to the various servers via FTP but the directory/file structure fails to load depending on the IP Address that MTN assigns to my computer/connection. (In other words, the FTP process does not progress past the MLSD Command and therefore fails to load the directories/files.)
The only way to get this to work is to disconnect my MTN connection and reconnect. I often have to repeat this procedure many times and sometimes over a considerable period of time before I am finally assigned with a "good" IP address that does not "cause" this aforementioned problem.
Most of the various MTN IP addresses that I have been assigned with to date are Guilty and "will not allow me" to view my directory structures. There are very few MTN IP addresses that I have been assigned that are Not Guilty as they do not cause the aforementioned problem.
So far I can confirm the following:
- I have two personal standalone computers (they are not connected in a network). I experience this problem via both of my computers.
- I connect to the internet by plugging the MTN USB modem directly into a computer's USB port.
- Both computers are running Windows XP PRO SP3.
- The problem is not related to my (client side) firewall. I have gone so far as to disable/disconnect and even uninstall the firewall and antivirus software. (I have also disabled Windows Firewall).
- The Sever side firewalls are not blocking the IP addresses because I have asked the various hosting providers to check this, and I am always able to connect to the servers via FTP.
Does anybody know if MTN has any control over the blocking of my ability to FTP files and why I am prevented from doing this via most of their dynamically assigned IP Addresses but not all of their dynamically IP Addresses?
If you suspect that the problem lies with MTN and it is within their control then could you advise me accordingly so that I know what to tell MTN to look for, otherwise I will just go around and around in circles without making progress?
If you suspect that the problem is not within MTN's control, then what do you think is responsible for this problem?
If there is a way to configure "Windows XP" to forcibly connect with or switch to a "good" MTN IP address that I predefine, then please advise me on how to do this?
I would be most appreciative for any suggestions/advice.
