title: vmware: unable to ping using NAT IP address, but can ping physical IP
body: <p>I've been searching around and found no similar issues have been asked.</p>
  
  <p>My desktop (windows 7) is in LAN, has IP (192.168.3.121).</p>
  
  <p>I installed vmware (windows 7), using NAT connection (172.168.174.128). The guest is able to access internet without problem.</p>
  
  <p>In guest, if I "ping 192.168.3.121", this will be ok.
  If I "ping 192.168.3.xxx", will also be ok.
  If I "ping 192.168.174.2" (DNS), this will be ok.</p>
  
  <p>If I "ping 192.168.174.1", can't ping.</p>
  
  <p>Note my host Vmnet8's ip is indeed 192.168.174.1. Ping from host also doesn't work.</p>
  
  <p>From host:
  "ping 192.168.174.128" (guest IP), does not work
  "ping 192.168.174.2", does not work</p>
  
  <p>Both host/guest windows are installed without any other "security/defender/firewall" related softwares.</p>
  
  <p>Anywhere can go wrong?</p>
  
  <p>Thanks.</p>
