Hi,

I red an article from Tom about FTP and a tri homed ISA Server. Tom said
that whan you want to have a FTP Server on a public DMZ, you have to
create two paquet IP filtering: one for the port 21 for the DMZ, and
another one from the port 20 of the FTP Server (if we use a FTP actif
client). But, why create 2 filters, and not only one filter with a
protocol definition with secondary connection ?

thanks.
