Setting up ftp client for active mode behind firewall

[lozina]

Hey, I downloaded FileZilla FTP client and during I'm trying to set it up to work in active mode through the program's network configuration wizard but I cannot seem to get it to work. There is a 'test connection' part at the end and I always fail active mode.

In the FTP client software there seems to be one two settings related to active mode- my server's external IP and a range of ports. So I look up my ip via one of the "whatsmyip" web sites and then I plug in a range of 1000 ports (I randomly picked 53500 - 54500)

Then I went into my firewall setup and into the port forwarding section. I forward that range of ports to the PC my ftp client sits on, and I left any other options to all (all WAN addresses, all protocols).

But it does not work. When I run the FileZilla test connection function, I get this:

PREP 54308
Response: 200 Using port 54308, data token 1400910216
PORT <my ip address>,212,36
Response: 502 Port mismatch. Tainted by router or firewall.
PORT command tainted by router or firewall.
Connection closed

The problem is that you do not know which new port the server would decide to open and thus can not open it through your Router.

If you are willing to take the risk, put the computer on the DMZ.
