IIS 6. Server 2003, Linksys Router and FTP--Passive Probs!

[garynyc]

Oh man, where do I begin? OK—I am an internet dilettante, so maybe you folks can help me out! I need to configure my system so that people can access my FTP site from within a web browser, which I haven’t been able to achieve. I am running Windows 2003 Server off of an old PIII 800 MHz machine, behind a Linksys BEFW11S4 wireless router. I have another PC on the router as well for surfing the net. So, I have set up the router for port forwarding of 20 and 21, as well as enabling ports 5100-5700 for passive connections , and have as well configured 2003 server with an FTP site through the IIS Manager. I have even done a registry edit from Microsoft to free up ports 5100—5700, matching the settings for ports I have configured in my router…here is the official link about how to do that with a regedit: http://support.microsoft.com/default.as ... -US;196271 .In addition, I have enabled UPnP forwarding on the router and enabled HTTP and FTP settings to go to my server’s local IP. I have a dynamic IP from Time Warner cable, and I have a program from no-ip.com to update my DNS info—both for my website which I host as well(which works fine) as for the ftp site.. OK…I can access the FTP site through an FTP client like cute ftp, but only using a PORT setting—I can upload and download no problem. Passive connections seem to get kicked off. People have been ULing and DLing successfully so far in PORT mode only. When I try to log in to the FTP through any web browser, a username/password box pops up, I enter the U/P that I set up(with permissions) and I get a message “426 Connection closed; transfer aborted”. When I look at IIS current sessions, it shows I am logged in for a couple of seconds before I’m kicked out. Is there a problem in getting web-based ftp connections due to a passive issue? Maybe one of you folks can straighten this mess out before I lose my hair! I am getting to hate Linksys and Win2K3 Server!

THANKS IN ADVANCE!

The following info is from our FTP Server page:
modules.php?name=FTP


Open up the Forwarding tab. You will need to make two entries. The first is the
port you are going to use as your ftp server and one port less. For this example, our ftp
server is going to run on port 7000. This means we forward port 6999 and 7000. Now
we need to forward a passive mode range of ports. I have forwarded port 50,000 to
50,100 which will allow 100 ports to be open at one time. You can forward as many ports
as you like, but 100 should be sufficient for home use. Each of of these should only have
TCP checked, UDP is not necessary. The IP Address should be set to the machines IP
address that is going to run the FTP server. Make sure the Enable box is checked. If your IP address changes on
the machine your running your ftp server on, you will need to update the IP address box
in your router each time your IP address changes.

Try opening port 80 for your (their) browser
