This is due to something called PASV mode. Passive mode (PASV) uses random connections (and "typically" random ports) to connect to the ftp as well as port 21. PASV mode works by allowing FTP clients to initiate sending of both control and data messages. Without PASV, FTP servers initiate the data requests only.
There are 2 ways you can get around this.
Your friends can either disable PASV mode on there FTP client or in web broswer. Disabling passive in IE is done in tools -> internet options -> advanced -> browsing -> use passive FTP.
You could also set up your FTP server (I am not very familiar with IIS as I use a 3rd party application) to only use a certain range of ports for passive and then have that range of ports forwarded on the router.
Hope this helps, oddduck
