Not really what you asked but... You *really* should consider the risks of running this with just router ACLs. It is certainly possible to lock Exchange into specific ports for its RPC traffic (look at MS site for papers about running it through firewalls) but this would be a lot easier / more secure if you looked into a VPN between the routers. You did not specify, but I can infer (possibly incorrectly) that you are connecting over a non-trusted link (gulp...) and you should seriously look at more than port-based security. You might even be able to set up IPSEC using PKI (are they W2K3 servers?) although it would really be simpler with a FW & VPN link. Just my 2c...

Fastest way to generate port info to build acl protection? 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 wt ------------------------------------------------------- This SF.Net email is sponsored by the JBoss Inc.
