What do we need to do to make FireWall-1 to recognize FTP service on
different ports (e.g. port 6005, 7005), we found some information about this
topic at
http://www.phoneboy.com/fw1/faq/0158.html
and it works but there is a problem cause this works doing a translate of the ip
of the client to the ip of the external interface of the FW, and translate the
service of FTP to the number of the port we want to use, cause we need to
stablish 2 different connections of FTP service but in different ports (e.g.
port 6005, 7005), from de same source client machine to the same destination
server FTP, the address translation rules has the next 2 rules
