Not able to ping from one Host Virtual machine to different host Virtual machine in Vagrant

I am not able to ping between two virtual machines on different Host, But can ping between two virtual machines if they are in the same Host machine, using a Bridge network to communicate between the two different VM’s.

Vagrantfile look like this on both VM,

ENV['VAGRANT_NO_PARALLEL'] = 'yes'
 
Vagrant.configure(2) do |config|

  config.vm.provision "shell", path: "bootstrap.sh"


  MasterCount = 1

  (1..MasterCount).each do |i|
    config.vm.define "kmaster2" do |masternode|
      masternode.vm.network "forwarded_port", guest: "80", host: "5050", auto_correct: "true"
      masternode.vm.box = "bento/ubuntu-20.04"
      masternode.vm.hostname = "kmaster2.example.com"
      masternode.vm.network "public_network", ip: "172.16.16.50", bridge: "ens160"  
      masternode.vm.provider "virtualbox" do |v|
        v.name = "kmaster2"
        v.memory = 2048
        v.cpus = 2
      end
   end
  end

please refer to the text diagrams below Ping between the Physical machine (241) and Physical machine (242) works ping between VM-11 and VM-12 within the same physical machine works. Ping from VM-21 in Physical machine (242) to Physical machine (241) works But ping between VM-11 and VM-21 does not work. Also, ping from Physical machine 241 to VM-21 (in Phy machine 242) does not work

Any leads would help.
