Ftp server


What is the name of the software? Is that an FTP software?
Anyway if you are using DX-E401 Router you can enable DMZ (demilitarized zone) to your PC.

1.access your router configuration page (default ip: 192.168.0.1)
2.go to advanced tab
3.select DMZ
4.select enable then type the ip address of your server pc
5.apply settings

after that have someone try to access the files in your pc.
if the software you installed is ftp software then have them access it by this

ftp://internet_ip

the "internet ip" is the ip address found in the STATUS TAB of your router under the WAN catergory.


If this software you mentioned is using any particular application ports, you will have to open those ports for your server PC.
In that case you will to configure VIRTUAL SERVER. It's the actual term used by dynex. for you to have a general idea how to configure your pc behind your router please go to this link

http://www.dynexproducts.com/skins/skin_1/Topics/Documents/DX-E401_Manual.pdf

Virtual server configuration is in pages 22-23. It has detailed explanation of the terms used.

Hope this helps!

set up ftp server behind the router


you need to set port forwarding for the correct ports, the default port number is 21. so you need to forward port 21 for 192.168.1.50

then go to www.whatismyip.com

copy your ip and add" :21 " without the " " in to the address so it looks something like this: 85.76.240.1:21

now your friend should be able to login from internet explorer for examble after typeing ftp://yourip:21 or from my computer by typeing ftp://yourip:21 into the address bar.

if you need more assistance let me know. im here to help.
Also if you are intrested we can try remote assistance to solve the problem but I would like some compensation for my time with remote control.

FTP problems.


There are 2 ports used for FTP. They are 20 and 21. When you initiate a connection that occurs on port 21, but data traffic is on port 20. Your firewall sees your outside FTP server trying to 'initiate' a connection on port 20 and breaks the connection to that IP address.
What you need to do is either use 'passive' ftp or open both ports 20 and 21 for ftp traffic in the firewall.
