Unless you have some preference for wu-ftpd I'd use vsftpd as it has a much
better reputation for security and bugs.
Unless you have some specific reason I'd go even further and not use ftp at
all, instead use SSH - it's more convenient and more secure anyway.

Things to check:
1) Your ISP isn't blocking in bound FTP, as some do.
2) You are using passive FTP, normal active FTP needs two ports and doesn't
usually work well through firewalls or NAT.
3) You don't have some exclusion/inclusion rule on the wu-ftpd (I don't know
where they are kept).
4) Check the firewall on the PC, make sure FTP is allowed from everywhere.
5) Have a look in the ftpd and firewall logs to see if there are any access
denied entries. You may or may not be able to check your "modems" logs.
Once you have all that checked. Try and nmap your box from outside the network
to see what ports it sees.
