If you do not have an ISA server I don't recommend you to put a FE in the DMZ. It's a hard job to open the neccesary ports in the firewall in order that the FE connects to the BEs and the AD infraestructure. We don't have an ISA server and we have the FE inside. Anyway if you are brave take a look at one of my post called "Firewall ports to open for W2k3 Exchange FE talks to BE and DC". You can try and tell us. Hope that it helps!!!

I've seen arguement for both putting it in the DMZ and putting it behind the firewall. Just to give you a little info about our environment - we have 1 firewall w/ no ISA Server. I know Microsofts recommendation is 2 firewall w/ a ISA server in the middle and the OWA server on the internal network. Since we do not have a ISA server or a 2nd firewall what would be the best solution.
