I have setup rules which allows certain users to FTP. However they find that each time the FTP is either transferring very slow or disconnects.

Any idea why this happens? seem to be a known issue as others are also having similar problem.

Your help is much appreciated.

I had a similar issues, in which removing the FTP filter solved as a temp fix... Although the ftp filter should be used as it allows additional required ports etc to be opened still worked for me without.

Of course I only done this 2 days ago so havnt had a good look to figure out whats happening.

Could you please post your access rule as well as what order it is in the list and whats above it? Do these slow connections occur randomly or at a certain time? How must additional traffic is going on at the same time?

Hello Steve,

Thank you for your help.
Basically we have three arrays in which each has a access rule for FTP. This issue occurs on all three arrays but for which EMEA the filter is unticked. I have unticked this also now for the APAC array and requested the office to test.

Furthermore the rule in APAC is nr 4 out of the 6 access rules that we have and is on top of the outgoing HTTP/HTTPS rule. Above the FTP access rule we have company specific access rules.

For EMEA the FTP access rule is nr 22 and the outgoing HTTP/HTTPS access rule is nr 7.
