Google compute engine static IP can't ping issue

I use the Google compute engine service and have configured a static IP for the instance.

The firewall uses the defaults open tcp:1-65535, udp:1-65535.

But use localhost can't ping to instance.

It's like a Google compute engine firewall setting issue, but I don't know how to change the settings.

ICMP could still be blocked. Are you using ping from your local computer to access the server? Are you able to connect to other services (say, a TCP service)? – Taj Morton
The ICMP none blocked. I used local computer ping other server ok! but ping my google compute instance no reply, all packet missed. – PinLiang
Are you sure you unblocked IMCP? Google has instructions here: developers.google.com/compute/docs/… Try running gcutil --project=myproject addfirewall icmpfirewall --allowed=icmp # allow ICMP traffic on your instance. – Taj Morton
Great!!! your comment are right! the default setting have ICMP but it's internal IP, not allow external access. It need add firewall icmp rule for "0.0.0.0/0", Thank Taj Morton reply. – PinLiang

In cloud console networks panel's "Protocol & Ports" field, you will need to add "icmp" to make it ping-able.

for example: tcp:80,443;udp:5000-6000;icmp
