Emacs FTP and BlackIce problems?

[Siegfried Heintze]

My client's web hosting service uses a fire wall called black ice. I used
emacs/ange/ftp extensively to edit files on live site but I constantly get
black listed with black ice and I need to use DHCP to get a new IP address
from my ISP.

I an only suspect that emacs/ange/ftp is the culprit because that is pretty
much all I use.

Is anyone else having these problems? Is there a fix?
