need ftp help

i installed serv-u ftp and my other computer a mile away (which is connected to my router) because i'm trying to get a huge 6gb file from there to this computer. anyways i connected to that computers system IP (192.168.0.101) from my laptop which is connected the same router to check if i installed my ftp properly, and it worked! so then i went whatismyip.org so i could get the internet IP and now it doesn't work! i did forward port 21 to the 192.168.0.101 ??

Am I missing something? the ftp worked over the network and I forwarded properly..

Someone please help!

 

Sure your ISP isn't blocking port 21? Most ISP's block certain ports for residential or non-business internet users so that users can't set up ftp servers, web servers, database servers, etc at home and consume large amounts of bandwidth. It worked within your own network because the network traffic didn't have to be routed outside of your own private network

 

Why are you setting up FTP on the WAN, wasn't this just for a local file transfer? And can you list your firewall rule(s) that you have setup for your router?

 

my problem still isnt solved, but thanks for the replies !

its not for local file transfar, the wireless laptop thing was test to see if the ftp worked properly. What I really need is for it to work from one ISP to another.. Doesn't the laptop thing rule out my firewall blocking it ?

I supposed that could be possible but I have the same ISP package over here and I remember a few years ago I used serv-u ftp and it worked fine...

 

Can use the following link to test if port 21 is open

Here another link for testing FTP http://www.g6ftpserver.com/en/ftptest

Generally once you have a PC setup to be a FTP server, Router pointer set, FW hole for PC, you must use passive mode to go through a FW. I prefer to use FTP client software like FileZilla.

 

thanks both of you
i couldn't do the first one link (canyouseeme.org) because I want it to check a diff IP than mine, but for the second one here's what I got:

Code:

* About to connect() to 69.157.241.58 port 21
* Trying 69.157.241.58... connected
* Connected to 69.157.241.58 (69.157.241.58) port 21
* FTP response reading failed
* Closing connection #0

does that mean my ftp isnt working?

 

It either failed on auth or setting not allowing, need passive mode if FW.
