    I need some help trying to figure out this issue:

    When a user tries to connect to an FTP they are placed on a firewall block right after trying to connect or perform upload/download.

    I was using the following FTP server configuration:
    TLS Encryption Support: Required (command)
    TLS Cipher Suite: HIGH:!aNULL:!eNULL:!PSK:!RC4:!MD5:!aDH:!DH:!SSLv3:!TLSv1
    Allow Anonymous Logins: No
    Allow Anonymous uploads: No
    Max Load for anonymous downloads: 4
    Max idle time: 15
    Max connections: 50
    Max connections per IP: 8
    Allow logins with root pass: No
    Broken clients compatibility: No

    I have switched it to:
    TLS: Encryption Support: Optional
    TLS Cipher suite: HIGH:MEDIUM:+TLSv1:!SSLv2:+SSLv3

    Anyone has any idea as to what could have been causing it? Was it TLS Encryption support?

    Thanks in advance!

    Hello,

    Are you using custom firewall rules, or a firewall management utility such as CSF? It's really the firewall rules or firewall logs (in the case of CSF) you will need to review to determine why accessing FTP resulted in a blocked IP.

    Thank you.
