This question already has an answer here:
I've configured FileZilla server successfully (without SSL/TLS) by port forwarding:
-Modem (external ISP address): TCP 21, 990, 50000-50100 -> 10.1.10.10
-Router (external 10.1.10.10): TCP 21, 990, 50000-50100 -> 192.168.1.61 (server)
And allowing Windows Firewall TCP(and UDP) ports 21, 990 and 50000-50100. I also set FileZilla server to use a custom port range for passive mode (50000-50100)
As soon as I enable the following checkboxes in FileZilla server:
- Enable FTP over SSL/TLS support (FTPS)
- Allow explicit FTP over TLS
- Disallow plain unencrypted FTP
- For PROT P to encrypt file transfers in SSL/TLS mode
The connection is made (accept the certificate), but the client fails at the
MLSD command after entering passive mode.
Does explicit SSL/TLS use different ports? If I try implicit SSL (port 990) the connection isn't even made. I would settle for either type of secure connection working.
