Hello, I install an ISA Server which has to filter and route Oracle Traffic between two DMZ's. At the begining, I have configured that the only port that had to pass through the ISA firewall is TCP - Port(1521)- Inbound. I've created a packet filter with this configuration, I've tested the filter with a TNSPING and all seems to be right, but a DBA tell me that there are another port to enable. I've tried to Which ports I have to enable?
