my computer is behind the litle d-link router where ports 20 and 21 are enabled, also tcp and utp ports are enabled in the software firewall:

the facts are:
- ftp upload & download will work with dial-up users. (working corectly)
- ftp download will work for my job computer which is behind firewall, but no upload , lmao (no problems with any other ftp account on this machine)
(list & delete is no problem with both connections)

any ideas on what i might miss?

tia

edit: did some more testing and dial-up users have no problems..., where do i search for the problem? (i tryed several different servers, configurations, ect..., seem like everything will freeze with the STOR ftp command.. - 'opening data connection' displays 4ever.)
