Network Interface Configuration for Backup LAN

Hello.

I use Backup Exec 2014 and this backup server have 2 NIC interface.

1 is used for service LAN (192.xxx.xxx.xxx) and another 1 is used for backup LAN (10.xxx.xxx.xxx).

I would like to choose backup LAN for backup connection.

I was able to find "Network Interface" configuration on "Defaults and Application Settings" screen of Backup Exec option.

But I was not able to find "Network Interface" configuration on backup job screen.

What should I do for showing this configuration ?

Thank you so much.

Taka.
