Can OMEnt support multi home networking?

Hi All, I want to join some network for my OMEnt OVA. Because one network is accessible internet and we can access via remote site, but there is not management network. All devices management port are on the other network, this network can only local. OMEnt v3.1 users guide written below. How can I add vNIC? I can't get the operate information. NOTE: If you have more than one IP for OpenManage Enterprise by using vNIC, you must use only the IPv4 address that is indicated in the Current IP Address field (click Application Settings > Current Settings ) for accessing the REST API. Best Regards.
