Hello!
You want to check out the "Configuring networks doc" on Powerlink. Page 15 has an example that might fit.

Example C: Calculating service ports in a multihomed environment
Figure 3 in this example depicts an environment where each NetWorker client uses two Network Interface Cards (NICs). One card carries regular production network traffic, while the other card carries backup data (control data and savestream data). This is known as a multihomed solution. A multihomed solution can increase backup speed by providing a dedicated network for backup data.
In this example, a storage node is set up on each side of the firewall so that client savestreams do not have to pass through the firewall. The only data that must pass through the firewall is control data between the NetWorker server, clients, and storage node. In this way, the firewall is relieved from the burden of processing data-rich savestreams.
Clients A, B, and C send the save sets to storage node X. Clients D, E, and F send the save sets to storage node Y. The NetWorker server and storage node X each have a tape library and six drives. Storage node Y has a tape library with only three drives. The hosts table is illustrated below:
192.167.10.101 client_A1 # NIC 1 for production network
192.167.12.101 client_A2 # NIC 2 for backup network
192.167.10.102 client_B1 # NIC 1 prod. network
192.167.12.102 client_B2 # NIC 2 backup network
192.167.10.103 client_C1 # NIC 1 prod. network
192.167.12.103 client_C2 # NIC 2 backup network
192.167.10.104 client_D1 # NIC 1 prod. network
192.167.12.104 client_D2 # NIC 2 backup network
192.167.10.105 client_E1 # NIC 1 prod. network
192.167.12.105 client_E2 # NIC 2 backup network
192.167.10.106 client_F1 # NIC 1 prod. network
192.167.12.106 client_F2 # NIC 2 backup network
196.167.10.124 storage_node_X1 # NIC 1 prod. network
196.167.12.124 storage_node_X2 # NIC 2 backup network
192.167.10.125 storage_node_Y1 # NIC 1 prod. network
196.167.12.125 storage_node_Y2 # NIC 2 backup network
192.167.10.126 NW_server_Z
As in example A, the firewall is bidirectional, blocking traffic from right to left as well as left to right. Additionally, there are no NetWorker clients earlier than Networker 7.3, no modules, and no requirement to use NMC or the client configuration wizard in the firewall.
