Has anyone implemented the below design and got it working without any issue:
ISA 2004/06, Edge Transport & Hub Transport
When you installed the ET and HT together inside the firewall like ISA, do you open all traffic first in the first instance so that ET and HT can communicate to the Mailbox role.
If successful, then allow only outbound and inbound traffic to go through to ET , HT , Mailbox server?
Putting the ET and HT in the DMZ is not any easy task, what other consideration I have to take to make this design to work succesfully (e.g., ligh weight ad)
Consolidating ET and HT role a good practice?
Appreciate your help.
