Hello, I'm trying to enable FTP on my Web server but I think there is a little problema during nat from the firewall.
I've my firewall (Zyxel USG210) with the following setting
External IP 217.111.x.X and the following role :
From External Ip on port 22xx nato to Webserver on port 19
In my web server I've ftp Site on port 19
Web server is on DMZ Zone.
When I try to connect using FTP app from my phone (the problem exist also for connection using filezilla) in Ftp Current Session I see my call from the ftp client
But I receive Connection Time out.
What I can check ?
Someone could help me to solve this problem?
P.S. Using Core FTP all connection works fine but I want to migrate to IIS
Thanks in advance
