Hi all,
I have a FTP server (CentOS + vsftp).
When I connect this server directly to internet it has an upload speed of 30 MB/s.
When I put the ftp server behind UTM 9.3 with NAT it has an upload speed of 2-3 MB/s?!?!
The Web Protection is off, IPS is on but I made an exception for this FTP server (from and to).
Also an exception made in Advanced Thread Protection.
How is it possible that it is 10 times slower behind the firewall?
Does someone has an solution for this?
