My client just installed an Oracle web application on a web server in the DMZ. The web server needs to connect to the Oracle DB server on the internal network. The developer said that the app will communicate on ports 1521 and 1526. I added the rule to allow the connection with those ports specified as the service. The app cannot connect. The log on the FW-1 shows the initial connection on 1521, however the app also tries to open a connection on a random port in the 1850 range which is dropped. About a minute later the 1526 port opens but the app still fails. Anyone dealt with this before? I have him checking into why the app uses three ports; 1521, 1526 and an 1850 something but was hoping one of you have dealt with this and can point me in the right direction. thanks!
John
