Using 2 ISA Servers in different DMZs - 9.Oct.2008 12:23:51 AM

We have a multi-tiered DMZ architecture with a New Exchange 2007 internal infrastructure. Is it possible to use a ISA Server in the External DMZ as a Reverse-Proxy ISA to pass traffic to the internal DMZ ISA that will have access to the CAS/HUB Servers on the internal network? The following things need to go through this configuration HTTPS and SMTP

Please help!

Any chance of a network diagram?

Are you trying to setup an inbound reverse proxy chain or is the internal DMZ ISA just a simple back firewall? E.g. do you want the external DMZ reverse proxy to proxy traffic to the internal DMZ reverse proxy, which then in turn proxies to the CAS servers?

Cheers

JJ
