System info:

Windows XP Professional
Norton Internet security (ie. including firewall)
WS-FRP LE (1999-2000) - file transfer program

Years ago I was able to use WS-FTP to upload pages & images onto the WWW with no problem.

I haven't had to use it for a while though, and I went in the other day to log in to upload an image and I couldn't log into the WS_FTP pgm. It just stayed motionless, trying to connect for minutes and minutes until I just cancelled and tried again etc.

I'm thinking that it can't get through the firewall because I've probably got a new Norton product or at least some upgrades that have changed any system setup that was letting it work previously.

I've tried looking through the Norton help files but can't see anything.
I've tried calling their help line, but the only time I can call is in the evenings when they have all their help-line calls diverted to countries like India where the techo's can't speak good english and can't understand what I'm saying.

So .... does anybody know how I can change the firewall settings in Norton to let me be able to send files out-of-my-computer to get them online?

ANY help would be really appreciated .....

Have you tried disabling the firewall to see if that is what is blocking your connection? Are there any advisories in History>firewall activities or intrusion prevention that show as blocked?

It sounds like you have an issue with active mode FTP.

FTP works with 2 ports: 20 and 21.
Port 21 is used to establish the control channel: the client (WS_FTP) connects to the FTP server on port 21.
Port 20 is used to establish the data channel. In active mode, the FTP server connects back to the client (you). This connection is probably blocked by your firewall.
In passive mode, it's the client that connects to the server to establish the data channel.

In stead of opening port 20 on your firewall to allow active mode FTP, I suggest you try to instruct WS_FTP to use passive mode FTP. I don't know how you configure WS_FTP to use passive mode, that is something you need to figure out.

Thanks for both the replies - I had the setting on Port 20 already so that's not the problem ..... and I totally disabled everything on Norton and it didn't work either .....

...... so obviously a problem with WS_FTP ..... the problem is that it used to work and now it doesn't. I'll have to do some more hunting around.

thanks again
