Using Squid - can't seem to block FTP access

[member 141630]

Hi,
I'm using Squid 2.5STABLE6 (Fedora FC3).

All works fine but I can't prevent clients using FTP. Squid seems to allow full FTP access from Windows clients. Clients using IE5 and IE6 - example ftp://ftp.microsoft.com works fine. I wish to prevent my desktop users from having FTP access. The clients are set to be non-routable so they are forced to use the proxy.


I've tried the following:

acl all src 0.0.0.0/0.0.0.0
acl internal1 src 192.168.0.0/16
acl ftp proto FTP

http_access deny ftp
http_access allow internal1
http_access deny all


Any ideas anyone?

I also note with interest that FTP access does not create any entries in access.log.

Regards
