Anybody here having experience to install proxy server? For your information due to security reason i block all ftp connection to my network and only allow for specific countries, my problem now is, some of my user also from the blocked countries, so based on my reading, its possible to allow user from blocked countries to access ftp but must via proxy server, i'm totally blur and dont know where to start because i didnt have any experience on installing/setup proxy server, i dont know is it possible to allow on proxy server based on username, let say i have a user with username 'abc', on proxy server i can setup if the username 'abc', it will redirect to user 'abc' ftp server and so on and of course i have multiple ftp server on my network.
Please advice where i have to start and which application suppose to install to make my dream come true, currently i have to manually setup on firewall to allow user ip to access their ftp server. That will be hard when the user using dynamic ip for internet connection and every time user need to access to ftp, i have to ask user for the current ip.
Please help and thank you so much, i'm sorry to my bad english.
