Please help ,My instance on compute node can't go outside

 In my environment : I have 1 controller node(Public IP : 192.168.4.75 , Private IP : 10.0.1.20) and 1 compute node(Public IP : 192.168.4.72 , Private IP : 10.0.1.19) ,
installed package i'm already installed all nova-package in Controller node and installed only nova-compute and nova-network in compute node.
Now i get some trouble , My instance on compute node can't ping all public ip in my network and internet,But my controller node and compute node can ping public ip on instance that running on compute node.However,instance that running on controller node work fine.they can ping outside IP (all public ip in my network) and internet.Then i try to solve this problem by mapping security group
security groud that i already apply in all instance:
IP Protocol From Port To Port Source Actions
 TCP 8080 8080 0.0.0.0/0 (CIDR)
 TCP 22 22 0.0.0.0/0 (CIDR)
 TCP 80 80 0.0.0.0/0 (CIDR)
 ICMP -1 -1 0.0.0.0/0 (CIDR)
 TCP 53 53 0.0.0.0/0 (CIDR)

But it's can't solve this problem.
here're nova.conf and network config file below:

Thank you very much for helping and reply.
