I am facing trouble setting up backup from Networker vProxy to DataDomain over interface group.

Having ifgroup defined in DD with x.x.x.10 and x.x.x.11 IPs included, configured DD device in NW using x.x.x.10.

And it works well (eg it balances load and fails over among 2 ifgroup interfaces) as long as x.x.x.10 is up while backup starts. I believe the problem is that NW/vproxy should contact DD via some IP other interface independent of ifgroup when it starts backup, in order to obtain ifgroup IP configuration.

Then direct BOOST data over to these DD IPs. I have other management IP on that DD, but do not know how to direct NW to contact DD over management IP when starting job, then to send BOOST data to ifgroup?
