can i run my own personal FTP server over a regular desktop computer system with running Redhat 8.0???

there is one thing that may pose as a problem, i have a dsl connection going through a linksys network
will this cause a problem?? and if so, is there a way to fix this problem?

all i really want is my own ftp server i can host my files on, if there is any oher FREE way i can do his, id love to hear from you

thx
