[Snort-users] What tool? Fastest way to generate port info to build acl

Subject: [Snort-users] What tool? Fastest way to generate port info to build acl protection?
Date: Fri, 18 Nov 2005 14:30:50 -0600
Description: Our location is a remote site within the company.  I have a router 
installed between our cat4006 core and the company router where the two routers 
are linked by a cisco hub. I have another cisco hub which links the cat4006 and 
the other interface of our router. We have AD and exchange in the company where 
we have AD controllers and a exchange server at our site that communicates with 
the company's main servers.  I have two snort boxes running on windows xp on 
each of the hubs.

1st Goal: To map-document all systems and business traffic that needs to cross 
to/from our site.
2nd Goal: Create cisco acl to install on our router to permit for now all 
needed ports for goal number 1 and deny everything else
3rd Goal: Modify goal number 2 acl's to include the source and destination ip 
numbers

Looking: for the best/fastest low cost way to generate the info for goal number 
1.

Is there a app (prefer windows app if there is one) that can be ran in sniffer 
mode on my hubs that could generate all ports being used, port-ip, 
port-dest-ip, etc where i could then quickly come up with our business model 
traffic pattern to create a baseline acl security?

Does any one know where there are any template acl's to start this project?

Has any one used xacta acl manager program for controlling cisco acl's? Is 
there a better cheaper solution instead of this application?

thanks ahead of time
