Hello Jet,

Your post below is rather ambiguous but I'll try to answer your question.

Assumptions:
1] You want to do anonymous ftp via your netscape browser.
2] Your saying that you can do anonymous ftp to the webserver via the C:>
   prompt, but not with the Netscape browser.
3] Your Netscape browser connects first to your proxy server before going
   out into the Internet.
4] You want to solve your problem without bringing about other possible
   security issues. (We never get enough of 'em!  );^] )

Conclusions:
1] If my above assumptions are right, try to disable ftp proxying for 
   Netscape browser. On Netscape, go to:

   Options -> Network Preferences -> Proxies

   Check the Manual Proxy Configuration box and choose View to see your
   setup. You might see the number 33185 on the Port window. You can try
   to delete the values listed for the ftp service. (Just write down the
   original numbers there before you do any deletions so that if you later
   change you mind or if matters turn from bad to worse, you can simply
   go back to square one.) Click on accept and then try to do want you
   want to do.

2] Or better yet, go to the Properties window and make sure the rule
   Enable Passive FTP Connections is set to First. (I'm doing this from
   the top of my head so if I'm missing out something, kindly help us out
   here.)

3] Kindly double-check if you have a rule allowing FTP and HTTP services
   from your proxy server to & from the Internet and also proxy server
   to & from your Win95 clients. (I do not have an idea where your proxy
   caching server is, whether it is within or outside your internal net.)

Hanggang sa muli,
Drexx.
