FTP download issues

[rockysam39]

Hi



We are facing this issue since last few months. When we try to download any drivers from the Dell or HP websites , the download is getting re-directed to one of their FTP sites and then the download fails with either 'Page cannot be displayed' error or continues to try opening the page for eternity...
When I check the logs on the firewall ( SmartView Tracker ) I see all the FTP traffic from the source machine is passing the Firewall, and not dropped/rejected (not even by the Smartdefense). However , veryfew packets are getting dropped. One such log detail is as follows:-

Policy Info: Policy Name: INITC_FW_01-20071108-DH
Created at: Fri Jul 04 13:44:14 2008
Installed from: SmartCenter-1The Firewall rule for Internet is set to allow FTP traffic.
I have tried to check for logs of traffic coming from these FTP sites (i.e., inbound ftp traffic ) but I dont see any traffic at all.

I'm trying to figure out if there is any blockage on the Firewall or not, though I believe there is none.

Can anyone help me with any ideas to research this from the Firewall end or a better way to analyze these traffic?
Is there anything else I may check to see if the FTP download is getting blocked by the Firewall or Smartdefense?
