Re: Server using wrong passive port

I'm having the same issue using an 'require implicit ftp over tls' connection on port 990 with a passive port range of 60100-60200.

I can connect and everything is happy at first. But randomly it will change from using ports in my passive range to port 80.

Response: 227 Entering Passive Mode (xxx,xxx,xxx,xxx,0,80)
Command: MLSD
Response: 425 Can't open data connection.
Error: Failed to retrieve directory listing



Response: 227 Entering Passive Mode (xxx,xxx,xxx,xxx,234,203)
Command: MLSD
Response: 150 Connection accepted
Response: 226 Transfer OK

Any ideas?
