Cant see remote file/folder list

[highflyer100]

Hi
I can log on to the remote server ok but when it comes to updating file list i get the following:

230 User logged in, proceed.
SYST
215 UNIX Type: L8
Keep alive off...
PWD
257 "/" is current directory.
CWD /www\/
250 Directory changed to /www
PORT 192,168,2,2,110,210
200 PORT Command successful.
LIST
150 Opening ASCII mode data connection for /bin/ls.
426-Maximum disk quota limited to 307200 Kbytes
Used disk quota 3548 Kbytes, available 303651 Kbytes
426 Data connection closed, transfer aborted.
QUIT
221 Goodbye!

If i try passive mode I get an error saying "passive mode is not allowed on this server"

Any ideas?

I will fill you in on some more detail. I can make a succesful connection if I use a dial up connection to internet. My present connection is a group broadband scheme which is a wirless connection beamed from a local hill. I think there is an issue with their firewall/proxy as my IP is a private one. What questions should I ask my service provider to ensure a tunnel through their firewall for CoreFTP is established?

Yes on dial up it works ok with the following log, including the quota message, but it is a 226 this time.
It definitely seems that I need a public IP addy.

250 Directory changed to /www

My ISP has told me that a connection can not be made because the hosting company is using Windows servers and does not allow passive FTP. Seems to be a cop out to me, what do you think? They advised me to change my hosting company!!!
