ABR11 Storage Node with 2 IP's on different subnets

Hi,

I've been trying to configure my Win2K8 machine with two NICs on different subnets to backup hosts on different networks, but as soon as I configure the 2 IPs the managment server loses connection to the storage node (I can see that the storage node assumes the two IP's).

From Windows I can reach both networks so it's not a routing issue, ABR11 just doesn't seem to like it.

Anyone knows if this configuration is possible?

TIA
