In the second box, add exceptions to this rule (IPвЂ™s or network ranges that should be allowed to connect). In the first box, put an asterisk to block all IPвЂ™s from connecting to your server. Under Edit > Settings, click on вЂњIP Filter.вЂќ Just remember that anyone determined to hack you will eventually find the port your FTP server is listening on, so further measures must be taken.ДЄs long as you know the IPвЂ™s (or at least the IP range) of the computers connecting to your FTP server, you can set FileZilla to only respond to login requests from those IP addresses. This doesnвЂ™t necessarily secure your server, but it obscures it and makes it harder to find. Under вЂњGeneral settingsвЂќ youвЂ™ll see вЂњListen on these ports.вЂќ It should currently be on 21, but we recommend changing it to a random five digit number (nothing over 65535). To avoid being detected by the thousands of hackers constantly scanning for people like you with an FTP server, we can change the port that FileZilla listens on. Hackers will constantly scan the internet for hosts listening on port 21, the default FTP port. Securing Your FTP ServerДЄlong with configuring the user(s) with a strong password, there are a few settings within FileZilla that you can configure to further secure your new FTP server. To give the user further permissions, such as the ability to copy files to this repository, check the boxes beneath вЂFilesвЂ™ and вЂDirectories.вЂ™Д¬lick OK once youвЂ™re done setting the user permissions. By default, the user weвЂ™ve created is able to read files, list directories, and list subdirectories. Now we need to assign the user permissions for this repository. Once youвЂ™ve done that, a window like the one below will pop up, use it to select the directory you would like to share as an FTP repository.Д¬lick OK. Once there, click on вЂњAddвЂќ underneath вЂњUsers.вЂќ Enter the username for an account that another computer will be using to access the repository weвЂ™re setting up.Д¬lick OK once youвЂ™re done entering the account name, and then click on вЂњAddвЂќ underneath the вЂњShared foldersвЂќ section. On the left side of the window that comes up, click on вЂњShared folders.вЂќ
