Default FlashFXP behind a firewall doesn't work

Hi all,

* FlashFXP v[2 ].[1 ], build [924 ], [ ]registered, [ x]unregistered, [ ]pirated
* OS [ ] WinXP, [ x] Win2K, [ ] Win98, [ ] WinME, [ ] Other
* Running behind NAT/router [x ] Yes & Model [ ], [ ] No, [ ] Not sure
* Running firewall [x ] Yes, Name [ ], Ver. [ ], or [ ] No
* Running Antivirus [ McAffee 4.5.1 SP1] Yes, Name [ ] or [ ] No
* Network [ ] xDSL, [ ] CABLE, [ ] Dail-Up, [ LAN ] Other

additional info if related
* FTP server(s) name [ unknown ], version [ ]

I try to connect to ftp://othth@goldmine.myftp.org:39675 using a http proxy, but it doesn't work.
The proxy is: 203.121.0.12:80

I have to use a proxy because the firewall at work blocks all FTP ports but 21.
My employer is a big company with about 30000 employees worldwide, so I
guess that my client is behind a router and I am sure it is behind a firewall, but
don't ask me models/types of hardware...

I can connect through this proxy to any FTP server that uses port 21 (not blocked by firewall), like vr500003.onlinehome.de (see log).

But when trying to connect to FTP servers that use other ports, it doesn't work (see log).

I selected HTTP proxy in the preferences and entered address and port for the proxy.
Am I missing something else??
Can you help me please?

P.S.: The log doesn't tell that FlashFXP is using port 39675 when connecting to goldmine.myftp.org...
Is it assuming port 21 maybe...?
