Problems connecting to port 21

[Lucas]

For some reason I am unable to connect to anywhere on port
21. I know the ip i'm trying to connect to (my web site)
is up because I can get to it from friends computers and
from work. I can ping the computer and connect to it on
any other port, just port 21 won't work. It won't work on
anywhere I try to connect. I have Comcast Cable for my
internet and I run no anti-virus or firewall software
(including the windows ones) and my ISP refuses to admit
they block my outgoing port 21. Anyone have any idea what
could be blocking my outgoing connections to port 21?

I too am a Comcast customer who uses an FTP Host from home
to work. Comcast is more than likely NOT blocking the
port, although I've beeen told they strangle the bandwidth
on certain protocols (Ex: FTP, Telent. Both my FTP and
Remote Desktop got killed speed-wise when I switched to
Comcast agsinst my will.). Try looking in your task
manager for a task called inetinfo.exe. It is part of IIS
and will sometimes start on port 21, blocking any other
app. that needs to use it. Turn it off through the task
manager Processes tab, then try to connect. There's not a
lot of information that I could find in relation to fixing
this problem, if that's what it is. I still have to
manually turn it off everytime I boot up prior to turning
on my FTP host.

If I'm wrong or if anyone else has addtional information,
I'd love to hear it.

We have a small LAN in our home utilizing a Cable ISP.
The Router shows up the info that the FTP takes place using port 21
EXTERNALLY, but utilizes Port 20 INTERNALLY.
Try adding your IP# and Port 20 to Windows FireWall Advanced Configuration
tab calling it FTP as well.
Also in the Windows FireWall, you can add your FTP Client &/or Web Browser
to the list of allowed applications. Note you can add 'Allowed Ports' as
well.
