FTP Server is half-working

This is half-working  as explained below.

The FTP server is on 192.168.2.100
The client machine is 192.168.2.5
The router is a Belkin F5D6231-4.

Under its Virtual Servers, I have:
1.   GuildFTP  21-21 (inbound port)    192.168.2.100 (Private port)   AND
2.   GuildFTP  10000-10500  (inbound port)    192.168.2.100 (Private port)  

Under its Application Gateways, I have
1.       10000-10500 (Trigger ports)  10000-10500 (Public ports)
2.      21-21 (Trigger ports)  21 (Public ports)

In GuildFTP options, I have:
NIC:   99
Passive mode:  Custom IP (is pressed in)   Detect is not pressed in
Real IP address:  72.59.202.102 (changed for my security)  DNS is not pressed in.
Port range:  10000-10500

Firewall on machine with server:  Windows firewall.  Turned off.

Half-working:
When I upload a file, using ncftpput, I get this:
connect failed (errno = 10060.
Falling back to PORT instead of PASV mode.
do_dir.bat:                                              6.00 B    11.30 B/s
It works, but in this odd way.   (Turning Windows firewall on-off does NOT change behavior).

I have always used the following syntax VERY successfully  in all environments to get files:
ftp://smitphi:62019087@ftp.myftpserver.com:21/pub/bn30fl.exe
Now it fails.  IE just thinks and thinks and then fails.

Notes:
GuildFTP does show someone connected (when I use the above smitphi command, but no file is downloaded  it just times out.

These problems may have begun when I updated to SP3.   (windows XP Professional).

When using FIleZilla, I get this:
Response:      257 "/pub" is current directory.
Command:      PASV
Response:      227 Entering Passive Mode (71,58,213,108,19,138)
Command:      TYPE A
Response:      200 Type set to A.
Command:      LIST
Response:      150 Opening ASCII mode data connection for /bin/ls (1169 bytes).
Error:      Transfer channel can't be opened. Reason: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.
Error:      Could not retrieve directory listing
Command:      REST 0
Response:      425 Can't build data connection.
Response:      350 Restarting at byte offset 0.  Send RETR to initiate transfer.
Command:      PWD
Response:      257 "/pub" is current directory.

I suppose I could uninstall SP3 and see if that fixes it  but I need for it to work with SP3 anyways.
