how can I connect Anywhereusb2 accross VLANS

I’m attempting to connect an Anywhere USB2 device across VLANS on our network. I can access the web management page for this digi device from the server I need to connect to it but I cannot get the configuration utility to locate it. I have put the subnet of the VLAN the Anywhere USB2 is connected to in the discovery list and I have also put the IP of this device in the connection list but it will not find this device.
