Hi guys,

I am using Fortigate at Edge Firewall and created many access policies and traffic shaping policies, implented IPS signature. Block or allow access to certain workstations on certatin links.

Now I want to implent ISA Server as Backend Firewall to provide more security and the main objective is to get monitoring reports of users bandwidth usage.

My question is that if i implement ISA in this then how about the policies that i have on Edge Firewall, because after implementing ISA Sever the source IP address will be the External Interface IP address of ISA Server. Right?

Waiting for your replies.

Regards,
Bxperts

1. The ISA exytrnal address will only be used if the relationship you set between internal & external is nat. If you set it for routing - (vconfiguration - networks - network rules) then it won't.

2. ISA does not report on bandwidth - it is a layer 3 firewall and a layer 7 application/gateway; it is not a router so does not give a hoot about bandwidth usage (only ISA2000 had that option, it was removed from ISA2004 & ISA2006). What it does report on is traffic usage as in what sites visited, by whom and the protocols used etc; not upon how much bandwidth was used.

I see. So, this is the idea behind the scene. Our concern is only that how much data downloaded by a specific user in given time. I have seen one sample report of ISA 2004 and it will work fine with us.

Can I get any sample report to show my management?

You can download and test ISA2006 from the MS web site for a 6 month trial or, if you use virtual server at all, you down load the .vhd file that is already there. Alternatively, MS gives access from the same site to test labs where you could get a sample out put of the reports available.
