We are planning to install AA6. I am referencing the architecture layout here: https://www.netiq.com/documentation/....html#b1kch8de

We typically install web servers in a DMZ network and database servers on our internal network. The documentation references what ports are used, but does not specify what the client and server are for each connection. Does anyone have documentation on what ports need to be opened between the web servers and the internal db servers (each direction). I also would need to know what connections the web servers make to the internet? For example, which server would make the connection to trello for sms/phone?

Would it be better to put all four servers in our external DMZ?

We haven't finalized the purchase yet, but I can open an SR once we have that finished if that is a better option.
