Hi there.   I have a 4G connection and would like to have an FTP running for easy access to some files. However, my ISP blocks incoming connections so you are not able to reach the FTP server from outside the local network.   They will not open any ports on their end.   So I'm wondering if it's possible to use AirVPN portforward to open the ports needed and that way have access to my FTP server from outside my network?     Best regards NizeGuy
