I have a server in a data center running UnRaid, I had set it up for a Hypervisor and docker. I just like unraid for managing this thing. Anyway I go to setup a VM and about an hour later I receive an email stating there was abuse coming from my server. Apparently It was using a different MAC address then what was allowed by my account. so my question is how do I I guess share the 1 interface I have for my guest VM's, I know the easiest response here would be to buy some IP addresses from them but im trying to learn how this works in a DC as well so i would like to figure out if it even is possible. Anyone have this type of issue?

In network source select virbr0. That should assign an IP on the virtual bridge completely inside of Unraid.
