Protocol Rule

Dear All,

I have something here and i want to understand.

as i understood Packet filter is used to make a control on the Incomeing
Traffic which is comeing to the ISA server from the external users -
internet users-.

While the Access Policy which its include ( Protocol Rule, Site contenet
rule ) , is used to make a control on the outgoing traffic from the ISA
server which is the Signals of my Users which they are in My LAN - either if
the users is ( firewall client - Secure NAT Client- WebProxy Client ).

untill now , i think i am in the correct side, is that true ?

-----------------------------

second thing, when iam installing ISA, i am enable the Packet Filter to
Block the Traffic which is outgoing and incomeing from enter the ISA and get
out from the ISA server.

I am using Protocol rule to open the Ports in the Packet filter to allow the
clinets for example to access the internet.

for example, when i am make rule for HTTP, i am make a packet filter to open
the Port for HTTP only and this Port is open dynamic through Policy, while if
i made static IP-Packet Filter, i am open special Port for specific resons,
and this Port will be open always.

----------------------------------------------------------------------------------------------------------------------------------------

My question is, if i have a Mail server hosted in USA, and i am using SMTP &
POP3 , is there any way to open the Ports for SMTP & POP3 from using Prtocol
Rule , rather than Packet filter?

if so, what is the diffrence between them ?

==============================

second question is:-

on which directions should i made the static Packet filter for SMTP & POP3,
should it be Outgoing only or, incomeing only , or both direction ?


Can any one help please .

Best Regards,

.
