You could throw an OWA front end server in the DMZ, put certificate on as Ed suggests, and then wrap everything up in an IPSEC packet that goes between the front end and backend. Between the client on the net and the front end, you would use SSL, so just open 443.
-----Original Message----- From: Erick Thompson [mailto:[EMAIL PROTECTED] Sent: Wednesday, 17 September 2003 11:29 a.m. To: Exchange Discussions Subject: RE: OWA front end server - licensing and security Ed, I'm a little confused. You're recommending that I put in a front end server, but not in the DMZ? It seems to me that I might have to open a bunch of ports, but if the front end server is in the LAN, all ports are by default open. Just to clarify, I have one Exchange server which lives on my LAN, and there is an SMTP server in my DMZ that relays messages to the Exchange server. At the moment, I don't have any other Exchange servers running.
