We recently moved our websites over to a DMZ running on our Astaro v4 box. We can successfully access all the websites from both the internet and intranet. However, our webservers in the DMZ need to utilize a SQL server that's on our internal network. When the webserver attempts to connect to the sql server, we get timeout errors.
I've set two different rules in the packetfilter:
DMZ > SQL Service > SQL Server Allow
DMZ > InternalNetwork_ > All Allow
Neither one will allow the web server to login to the SQL server. Nothing shows up in the PacketFilter as being blocked when I make the SQL request. If I turn the above rules off, then the attempts are shown in the PacketFilter as being blocked.
From the SQL server itself, I can ping, tracert, and even connect to admin file shares on the web server in the DMZ, so it obviously knows how to get to the web server.
