Instance cannot connect to external network
Hello,
I am following this http://docs.openstack.org/juno/install-guide/install/apt/content/launch-instance-neutron.html (official tutorial)
I am in the part where I should check the external network connection and I have this:
$ ping -c 4 openstack.org
ping: bad address 'openstack.org'
$ ping -c 4 8.8.8.8
PING 8.8.8.8 (8.8.8.8): 56 data bytes
--- 8.8.8.8 ping statistics ---
4 packets transmitted, 0 packets received, 100% packet loss
I cannot edit /etc/resolv.conf because it seems CirrOS doesn't have package manager nor any kind of text editor...
I can ping the router with the internal IP (192.168.1.1) and external IP (192.168.102.230), but I cannot ping the other IPs I already mentioned.
Here it is my network topology: http://imgur.com/vOUt3rz
How can I solve this? As I am following an official tutorial shouldn't the instance already have these issues solved?
---- UPDATE ---
Here there are some outputs:

Did you use a real GW when creating the external subnet? See here
1.When you created private subnet on which CirrOS VM is running , did you define IP of DNS Server of local ISP ?
2. From within VM run :- $ curl http://169.254.169.254/latest/meta-data
You are not supposed to run any
route add ...from within VM. It should work automatically after log into VM.Output from the following two commands would be helpful
@Antonio G., I followed the link you gave, so I used the gateway of the real network. @dbaxps, I cannot edit /etc/resolv.conf so I didn't define any IP of DNS. I know I'm not supposed to run any "route", however, it didn't come automatically... @jjulien, I will edit my question with the outputs.
