Hi!

I have installed DevStack on my laptop. I am able to ping/ssh from the laptop to the instances, and I can access internet from the instances(ex: ping 8.8.8.8). Here is my problem, what should I do to let other computers be able to access the instances?

I have:

  • A laptop that has DevStack installed: 192.168.2.150
  • The instance of openstack: 192.168.0.5(private), 172.24.4.5(floating)
  • A computer: 192.168.2.188

Now,

  1. The laptop can ping the instance.
  2. The laptop can ping the computer.
  3. The instance can ping anywhere(ex: 8.8.8.8, the laptop and the computer)
  4. The computer(192.168.2.188) cannot ping the instance(172.24.4.5)

I saw some questions have similar issue

(sorry I cannot post links)

Unfortunately, I still have the problem. Any advice and suggestions will be appreciated.

Thanks!
