Network issue with Hyper-V

Question

I have done a setup of a lab Windows 2022 with Hyper-v and a host inside of that
I have 2 network cards with an ip adress of .20 and .30 on these cards.
I've created a virtual switch and added this to one of the cards.

Created a VM that is connected to the Virtual Switch my ideas was that the network card in the VM should have .21 as the ipadress.

But I'm not getting this to work, the WM can't reach outside and the host or any other machine can't reach the VM.

Is there any special settings that I need to consider?

I'm running this in WMWare vsphere is that the issue here so the network cards isn't compatible everything else seams to work?
