Artnet, Streaming ACN and PVP issues

I have a house of worship lighting system that is controlled via Vista 3 on a all-in-one PC and a wing. The lighting system is set to output sACN 10.x.x.x IP range. I’m hoping to trigger a PVP Mac from a separate Ethernet port (USB to Ethernet adapter) connected to the Vista PC so as to keep the systems isolated via ARTNET with a IP of 2.x.x.x/subnet 255.0.0.0. Whenever I attempt to assign/bind the PVP universe to the 2nd Ethernet interface on the Vista it kicks out the 2.x.x.x IP and assigns a generic 169.x.x.x. When I connect to PVP using another controller platform (Onyx) I have no issues. Any ideas??? PVP appears not to support sACN otherwise I would simply add it into the existing system via a network switch and be done with it.

typically 169. range is that the device can’t connect to DHCP

Well I have 2nd ethernet port attached to the Vista PC MANUALLY set to a 2.0.0.1 with subnet 255.0.0.0 and the PVP mac is MANUALLY set to 2.0.0.2 with subnet 255.0.0.0. The Vista DMX connection window initially sees the 2nd ethernet port I’m trying to use and shows universe “NOT ASSIGNED”. As soon as I attempt to assign universe on Vista to the ARTNET universe (in this case universe 4) under Vista “dmx connections” window the IP switches from 2.0.0.1 to a 169.x.x.x. IP for some reason… if that makes any sense. I have a 2048 dongle and nothing is patched to universe 4 Universe 1 and 2 are strictly ACN on the main ethernet port on Vista PC. Not sure why Vista won’t stay locked to my 2nd ethernet port once I assign universe. I assume Vista can output both ACN and Artnet simultaneously???.
