Min and Max ports having no effect

I’m trying to set up a ftp server behind a firewall, which requires that a port range be specified for pasv connections to go through. I’ve set up my vsftpd.conf as follows:

pasv_max_port=51000
pasv_min_port=50000

However, it doesn’t seem to be adhering to these rules, as evidenced by using ~200 range ports. When I try to connect this is the output:
