For each server, you have to run as root the following commands:
r1soft-setup --agent-bind-addr <ip>
/etc/init.d/cdp-agent restart
You only have to replace the corresponding IP for each particular service.
#For example for the service with ID V12345 and IP 192.168.1.0 you have to type as root the following commands:
r1soft-setup --agent-bind-addr 192.168.1.0
/etc/init.d/cdp-agent restart
#For Windows:
In C:\Program Files\Idera Server Backup\conf\agent_config replace BindTo=0.0.0.0 with BindTo=<ip> (replace the corresponding IP for that particular service.)
Then restart the backup agent from Backup Agent Configuration Utility>Services>Restart Server Backup Agent.
