PIX 515E DMZ and MS ISA 2004

Hi,

Need your feedback.Refer the attached diagram.This is as per my client requirements.

1. is it good to have exchange front end server on cisco PIX DMZ?

2. Exchange FE has to contact the domain controller,exchange backend server inside.

3.there is only one public IP and outside users access their internal mail using OWA(outlook web access).

I thought of changing the design by having ISA 2004 as internet firewall and cisco PIX with DMZ as internal firewal. what do you say?

thanks,

Prashanth

Pras,

I will stick to your original design or alternatively you can place your Exchange FE on the lan segment between your PIX & ISA but I prefer the ur original design.
