I've just tried moving our mail server - which is Microsoft Exchange running on an NT Server - from the PRO to the DMZ. Not surprisingly it didn't work because it needs to be able to contact its NT Domain controller in the PRO in order to authenticate people collecting their mail.
Without going into the details of the tunnels and filters I tried, the upshot is that I can't seem to open up any communication from the machine in the DMZ to one in the PRO. In fact, the console displayed warnings to the effect "attempt to access PRO from DMZ" which suggests that I'm attempting the impossible. But my only other alternative is to open a tunnel all the way to the PRO which I feel is less desirable than tunnels from EXT-to-DMZ and DMZ-to-PRO. Any suggestions would be appreciated. Our version of Gnatbox is 2.0.2b Thanks, Billy Dennigan. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Billy Dennigan, E-Mail: [EMAIL PROTECTED] IT Design (Ireland) Ltd, Phone +353-1-4967766 29 Kenilworth Sq., (Ext. 111) Rathgar, Dublin 6.
