Firewall between SAP application and database.

[Former Member]

Hi,

1. I plan to install Biller Direct Java instance and MS SQL server database across the firewall. Would that be an issue? What ports should be open for installation?

2. The R3 back end is also in the same subnet as the Biller Direct database in.If I use HTTP SSL for connecting Biller Direct to R3, what ports should be open?

3. What's the port for Jco connection between Java instance and abap instance? I know for abap instance we need port 3300, but what port it is when data send back to Java instance from abap?

Thanks.

Hi,

2. Can you give an example how the Biller comunicates with R3?

3. port 3300 is not enough it's only the gateway port you need to open the dispatcher port (3200) and also if you interested in load balanced connection open the msg serevr port (3600).

The ports that opened from the java side are random.

Hello,

We are too planning to add firewall in between SAP and Database instances.

So was this issue resolved already ?

If yes did you face any performance issue after adding firewall between SAP & DB instance.

And what all activities were performed for this.

Thank you, Regards,
