How to set up a ftp server behind a SMC 7004 router?

[Jeffy]

I connected 3 PC with a SMC 7004 router, and let them share a cable connection. My question is since the router assign an IP to each PC, and the IP is only useful with the intranet, how can I setup a FTP server and let someone outside my small intranet to access my ftp server?

Thanks alot.

You need to enable port forwarding which allows external WAN requests to be directed to an internal IP address. For FTP, this is usually port 20 and 21.

Good luck!
