im trying to figure out how to setup a home ftp server so other people and also myself can access a specific set folder with whatever i want to put in it. I am connected to a router and have opened all ports needed and setup a virtual server in router (FTP Server using port 21). I am able to access my FTP site on any computer connected to the router but noone else can outside my internal network.. im not sure why.. ive tried other programs as well (serv-u, cerberus)
