Helllo ,
We have 2 level of firewalls at my company. We have 1 DMZ sitting on the perimeter and a cisco firepower acting as internal/core firewall.
We have an exchange server that should be publicly be accessible. Where do you recommend putting the exchange? In the DMZ or behind the internal firewall?
A friend of mine told me that it is never a good idea to put an exchange server in the DMZ as I will need to open a lot of ports to make my exchange server talk to my AD server.
Any suggestions please?
Thanks
