I'm having trouble connecting to certain FTP sites from my work's PC. Most sites are fine, but it seems to be 2 sites I administer which are with the same host.

I can connect from my home ADSL fine, but when I connect from work, using CuteFTP it accepts the username/password, but then just freezes and disconnects:

Heres a transcript of an unsuccessful connection:

STATUS:> Connect: Tuesday 13:44:55 04-15-2003

200 PORT Command successful.

I've tried PASV mode on and off with no joy. Are there any other settings/configs I need to address?
