Exchange 2003 OWA over PIX 515
Posted on 2006-06-21
I need to provide OWA access to my roaming clients, they will be accessing published exchange probably a front-end server via a public network (via Internet). My exchange and ISA 2000 server is in "inside" interface of PIX 515, and using a TREND ISVW as my SMTP gateway which is in DMZ to forward all SMTP traffic to "inside" exchange server. But now all my roaming clients can not access WEBMAIL or OWA since there is no published server in our network. I was thinking having Front-End in "inside" network which will published over ISA, but our IT audit team is against to having connections to "inside" network. They are suggesting to use DMZ for WEB mail, but I am not convinced in their recommendation since there can loop poles as well. I hope exerts could help me in finding a solution to my requirement, as a option i can think of another web mail product but i was impressed with 2003 OWA interface. Please help me to find a proper solution without compromising security side of the network.
