Filezilla Cannot Connect to Server

I have been trying to figure this one out.

I have Host Definition for FTP Server IP Address

I have firewall rules setup to allow traffic from all of my networks across any service to FTP definition.

Firewall keeps Dropping and records random numbers on srcport. The entries are correctly identifying my IP, IP I am connecting to, and dstport: 21. Why is it using a random port number for the source port.

Because only the destination port ist 21 for ftp or 80 for http.

The client port is nearly everytime one of the >1024 ports.

Or am I understanding anything in your question totally wrong?

I think I understand: the source port is irrellivant? I have a Firewall rule setup to allow the destination IP over the destination Port, but it is still dropping. The only thing I could see that wasn't covered in the rule was the source (client) port. I am just trying to figure out why, within the last week, this has stopped working.

In which 'mode' is your ftp server working, 'active' or 'passive'?

Your FW rule is 'internal Network' using service 'any' destination IP of the FTP Server?

We have tried in both passive and active modes. Firewall Rules I have tried:

Internal Network - FTP: 21, 20 - FTP Server

Any IPv4 - FTP: 21, 20 - FTP Server

Any IPv4 - Any Service/port - FTP Server
