Urgent: What ports should be required in DMZ zone?


I am installing a SAP Biller Direct on top Netweaver 2004s. I installed CI and MSSQL_SERVER database in different host at the same subnet. Now we reassigned IP address of CI and moved it to DMZ zone. The DMZ zone is different subnet from databse server in. What ports should be open?

1. Between CI and database? I know from CI to databse is 1433. If I use SSL later, is there any other port for JDBC connection?

2. The sapmnt folder is on CI, how could database server access it? Any additional port?

3. From CI, we have JCO connection to R3 backend. What is the port of this? 3300? What port is it when R3 backend sending data back to Java CI?
