4.9 Appendix I – Configure the Firewall

To configure the firewall on a RHEL for SAP HANA system, you can use the system-config-firewall tool

(you will need an X11 System to display the GUI version, or you can use the -tui option for a pseudo-graphical

interface in the shell) or you can modify the firewall setup directly with iptables or indirectly by applying new

rules to the file /etc/sysconfig/iptables.

In the following description, we will use the direct method, with the iptables command. At the time of

writing, this step has not yet been included in the kickstart file.

4.9.1 Calculation of the Ports Used

SAP HANA uses several ports for different purposes.

Most of these ports have to be calculated based on the instance number. For the following ports, a database

with the instance 99 is used to illustrate the calculation.
