cannot ping but can ssh and http

[JacksonZheng]

Host: Windows 10 Guest: Centos 5 Network: NAT

Why: cannot ping in guest, but can http or ssh.

Debug:

1. use tcpdump in guest and host, will see icmp request is sent to host and host resent this packet to the target, but after got icmp reply, host will try to resent reply to 10.96.1.19, then return "unreachable network"

1. try to capture virtual machine packet by(there is only lo0 and eth0 interface in my guest):

VBoxManage.exe modifyvm "redhat32" --nictrace1 on --nictracefile1 c:\Users\xxxx\netlog.pcap But nothing is logged.
