Hi Ali,
Enable packet filtering and scan only from the external network.

        i am new to this group and my first mail, maybe you've already
answered this question...
        i have windows 2000 server and network and external connection
with radio link.
        isa sp1 is installed, windows2000 sp3 is installed.
        From protol rules i let all ip tarffic and from ip packet
filters i opened some ports like pop3, but when i scan internal and
external ip i cant see the ports that i let. Another interesting point
is if i stopped the isa server services and if i scan again i see the
same ports, so it seems isa doesnot decide anything.. 
        no another firewall is installed and ipsec is not enabled. I
have 3 ethernet cards. 1 is external and the others are internal.
        someone has any clue?
