Open the Firewall Ports¶

As of version 5.3.5, the firewall ports are no longer opened during the installation but have to be opened manually after the installation. For this, the separate script firewall.sh is contained in delivery and can be used for opening the firewall ports.

Change to the PLOSSYS 5 - 6.2.0.1691 - rpm directory and start the script for opening the firewall ports:
```
cd "PLOSSYS 5 - 6.2.0.1691 - rpm"
```
```
sudo sh firewall.sh
```
Hint - fewer ports for single server installation

In case of a single server installation fewer open ports are needed, refer to portlist for single server installation.
