Hi Angelo,

This should be possible. Make sure that eth1 is connected to the Vlan trunk
with necessary port configurations.

Create 2 network with segmentation's ID as 108 and 109 respectively. Create
the respective subnets for both network and then proceed with further
configurations as needed. Are you facing any specific issues here?
