Firewalld rejects server FTP response

Hi,

Just to clarify its firewalld on the client server (Rocky), not firewalld on the mediation FTP server blocking the connection?

If so, does the issue persist after issuing:

echo 1 > /proc/sys/net/netfilter/nf_conntrack_helper

Also:

If you can ssh to server, you can use SFTP:

Thanks Tom.
