Special Topology

Note:
The WAN port of TL-WR1043ND is linked to the LAN port of an xDSL modem. If the modem has
already obtained a public IP by dialing to the Internet with the username and password provided
from your ISP and TL-WR1043ND obtains its IP through Dynamic IP service provided by the
modem, the remote PC cannot reach the FTP server through the WAN IP of TL-WR1043ND
because the WAN IP of TL-WR1043ND is not a public IP in case of this situation. You can consult
the vendor of the modem to modify some settings to let the TL-WR1043ND obtain public IP or
assign a specific port for FTP server application with private IP.

which includes 3 folders (tplink01, tplink02, tplink03) and 3 files (test01.doc, test02.doc,

The following part would help you set up a FTP server and download the files from the FTP server
through a USB Flash.
