  Re: Ftp connect only selected ip es Please do not post support questions in General Lounge. General Lounge is meant for off-topic conversations that are not about cPanel. This question is related to something that is part of cPanel, so I moved it to a more appropriate section. You can restrict access to FTP in the WebHost Manager, in Home " Security Center " Host Access Control. This is documented here: . Port 21 is the standard FTP port, and FTP clients expect to use it. Because of that, changing the FTP port is generally a bad idea. You can effectively restrict access using Host Access Control. Note that Host Access Control will not prevent an unwanted visitor from making a connection, but it will prevent it from logging in. Another option is to configure the iptables firewall on your server to block the unwanted IP addresses. cPanel does not provide a firewall configuration tool, so you may want to install a third-party tool like CSF or APF if you have not done so already. Information about those tools is available on their respective sites: [url=http://www.configserver.com/cp/csf.html]ConfigServer Security & Firewall

  You could do this easily with CSF, no need to change the port number Just close port 21 in csf.conf, then whitelist any IP addresses that need FTP access.
