RedHat Linux Firewall Setting for CommVault Backup

Problem Description : 

Linux requires specific firewall settings for communication and backup with the CommVault server. Ports 8400-8402 are used for control communication and other ports are used for backup data stream.

 Resolution : 

Our CommVault installation is setup to use ports 8600-8620 for the data stream. Instead of opening ports 8400-8402 and 8600-8620 individually (which also leaves these ports open to all other IPs), the following steps will open ALL ports between the Luinux server and the CommVault server.

1. Open console connection to the Linux server

2. Navigate to File System/etc/sysconfig and open file iptables in text editor

3. Add line '-A RH-Firewall-1-INPUT -s 168.26.240.11/32 -j ACCEPT (if CommVault changes from 168.26.240.11 use that IP instead)

4. Save the file

5. From command line, issue commans:

- service iptables reload

- service iptables save

Setup can be verified by opening System-->Administration-->Server Settings-->Services, clicking on iptables and reviewing the Status window. A Restart might be required to update the Status.
