Hi,

Disabling the FTP-Proxy will stop allowing your clients to access outside
ftp servers.
If you want this, you can disable, otherwise makes no sense.

After some research, i found a problem with some FTP Server running
Microsoft IIS.
Not every server is well setup, and the returned IP from server is the local
subnet IP.
If the server, that you want to connect has this problem, forget about
successfull connections.
You can't receive anything.

Sample using a Active Connection:

C:\>ftp nonono.com
Connected to nonono.com.
220---------- Welcome to Pure-FTPd [TLS] ----------
220-You are user number 2 of 50 allowed.
220-Local time is now 17:20. Server port: 21.
220-IPv6 connections are also welcome on this server.
220 You will be disconnected after 15 minutes of inactivity.
User (redebristol.com.br:(none)): remote
331 User remoto OK. Password required
Password:
230-User remoto has group access to:  ti
230 OK. Current restricted directory is /
ftp> ls
500 I won't open a connection to 192.168.0.2 (only to 200.99.99.99)
425 No data connection

But, using Passive Connection:

Status:    Connecting to nonono.com ...
Status:    Connected with nonono.com. Waiting for welcome message...

OBS.: Either WAN and LAN, FTP-Proxy was active to this samples above.
