routing Issue

[fluctuationit]

Hello. I have I think a simple issue but not easy when you start routing
OK I have a vsphere 6.7 with 2 vswitch
Public IP -> VM Network vswith (IP address WAN 212.83........)
LAN IP 192.168.1.1 All my VMS are connected to a second vswitch (name VMLAN)
My GOAL :
I need to add new subnet on my internal network
172.16.0.0/16
So I added a new NIC on my pfsene and I set up address 172.16.0.1
If I add a new Virtual Machine with IP 172.16.0.10 I cannot ping 172.16.0.1
so whats must I do to be able to ping the 172.16.0.1
I want people from outsite to be able to RDP the 172.16.0.10

Tks

Is the VM network adapter bridged or NAT? If NAT, you have the same subnet on both sides of it, which will not work.
