Assign IP Address for Windows Server 2025 VM on Hyper-V

I have built my first Windows Server 2025 VM on HyperV and trying to assign an IP address.  I want the VM's to be like an actual server so I Created an external vswitch.   The HyperV server IP is 172.16.1.41 with a physical gateway of 172.16.1.5.    I have tried to assign the new VM with 172.16.1.42/255.255.255.0 and the Gateway is 172.16.1.5 also.  However, I cannot get a positive ping.   Do I need another VSWITCH configured or what am I missing?
