How to configure PASV mode for Bulletproof FTP Server:

Put a checkmark on "Use passive mode IP"
If you have a Dynamic IP and if you are using Bulletproof FTP Server ( version 2.3.1 build 26 ) then go to Step 5.
If you have a Static IP and if you are using Bulletproof FTP Server ( version 2.3.1 build 26 ) continue with step 4.
If you have a Dynamic IP and if are using Bulletproof FTP Server (version 2.4.0 build 31) then go to step 3.
If you have a Static IP and if you are using Bulletproof
FTP Server (version 2.4.0
build 31)
then continue with the next step.
Choose "fixed IP"
Click on the little a.
Enter your OUTSIDE IP ( You can find out what it
is by going

Then click ok, then click on ok again.
(For this example, we will use the IP address of
121.24.96.36. Your outside IP
will be different.)

Step 2. To set a PASV port range,
The latest version of Bulletproof FTP Server
( version 2.4.0 build 31 ) does not allow you
to enter a PASV port range of 50000 to 50100. You
will have to edit the FTPsrv.ini file
( which is located in C:\Program Files\BPFTP Server
) and manually edit the two settings:
PASV_LowPort=50000 and PASV_HighPort=50100
.
Make sure that before you do this, shut down the server
first. Restart the server when you
have made the changes.
Enter your dynamic DNS server website address
(You can get one at no-ip.com) e.x. yourname.no-ip.org,
yourname.dyndns.org
Setup your PASV port range by doing step 2.

Step 4. Now we will setup a PASV port range .
