Firewall issue

[SAPSupport]

OS and network team are enabling the firewall.
We have application port but we don't have orale and maxdb related ports.

We are using oracle database, Maxdb database and Oracle dataguard for replication.

Please provide the list of oracle database, Maxdb and Oracle dataguard ports, so that we can share the same to OS and network team to enable the firewall.

The only explicit port is listener port 1521 or 1527, etc.
Then the other port is dynamic, and have very large range for example kba ##3193291
SAP note ##562403 point 23 explains the reason, why other ports are needed.
