First thing you'll want to do is get a firewall on that network (your description didn't mention one as being present.)  I'd actually recommend setting FTP up on a server in your DMZ (demilitarized zone) so it's not directly accessing your internal network.  You do this by using two firewalls (one separating the Internet from the DMZ and one separating the DMZ from the LAN) or by getting a firewall package that supports DMZs with a 3rd NIC.  Either way, you would use your firewall to allow port 21 access to a host on your network.

If it is just a router separating the Internet from your LAN, then I assume the hosts on your LAN have valid IP addresses (you are not using Network Address Translation).  You probably have port 21 access already to the hosts on your network.  In that case, you only need to install the firewall software.  What kind of operating system are you trying to install FTP on?  Most of the server OS's have FTP built in, and you might just need to enable it.  If it's something like Windows 98, you can try any of the Freeware FTP daemons out there like WAR FTP Daemon - all available from a place like www.tucows.com

I have a d-link router for my dsl/aln, and I set static ip's on my lan, and then forward port 21 (ftp) to my one machine and use serve-u ftp server from www.serv-u.com

Does your provider allow incomming requests on port 21?

Maybe you'll have to map the ftp port on a port above 1024.

Can you check this out?
