Squid Proxy server - FTP access problem

[AlphaTwin]

I don't remember ever having this problem before with Squid. I've been using it for many years now but with this new server I just built I can't download from a FTP site. I've tried several so it's not the site it's for sure my FTP, also it works fine if I bypass Squid.

the error in the browser is:

An FTP protocol error occurred while trying to retrieve the URL: ftp://ftp.fedex.com/pub/us/software/FedExShipManager_2361.exe

Squid sent the following FTP command:

    Connect to server data port

The server responded with:

Your cache administrator is root.

I've edited the .conf file and added the following and then restarted:

acl ftp proto FTP
acl ftp_port port 21
http_access allow ftp_port CONNECT

Any help would be great
Thanks

acl ftp proto FTP
acl ftp_port port 21
http_access allow ftp_port CONNECT

The above code looks to be unnecessary.

However, something has changed in this newer version of squid that I can't seem to find.

I've quit using FireStarter and started using Webmin to config IpTables.

It's very possible that I'm doing something wrong. I've included an image of my Webmin Linux Firewall config. Does it look OK?

Thanks again
