Linux Server iptables configuration for Symantec Backup Exec Agent
Iptables Backup Exec
Below you can find how to enable the backup exec agent ports on Linux iptables configuration.

Restart the backup exec server
Now login to the linux machine and enable access for this port range (31821-32829) and the Backup Exec agent
VRTSralus which is running on the port 10000 (default port for VRTSralus).
If webmin is running on the port 10000, Edit /etc/webmin/miniserv.conf and change the default port to 10001
Enabling BackupExec Agent Port
#iptables -A INPUT -p tcp –dport 10000 -j ACCEPT
#iptables -A INPUT -p tcp –dport 32821:32829 -j ACCEPT
Also you can manually edit and /etc/sysconfig/iptables and add the below mentioned line
-A INPUT -p tcp -m tcp –dport 10000 -j ACCEPT
-A INPUT -p tcp -m tcp –dport 32821:32829 -j ACCEPT
Now Save and restart iptables
# iptables-save > /etc/sysconfig/iptables
or
#service iptables save
#service iptables restart
In this example, the Port range, 31821-32829, specified in the Backup Exec network security settings is different than the port range, 32821:32829, specified in the iptables entry.
In Backup Exec 2012, the network security settings are in a slightly different place, but once you find them, this example works as described.
