Unable to connect to certain external IPs from VM

 

I have a really weird issue (or so it seems to me)
I installed OpenStack Folsom using the guide - http://docs.openstack.org/folsom/basic-install/content/index.html -
And and able to spawn VM get IP, set floating IP and now am trying to do some development within the VM.
I am unable to connect to certain sites and ports:
git clone https://github.com/openstack-dev/devstack.git - <-- This just times out.

This is what works:
Wget google.com
Wget openstack.com

This is what hangs and times out:
Wget yahoo.com
Wget paypal.com
Wget facebook.com
Wget github.com
ubuntu@fpatwa-1:~$ wget github.com
--2013-05-10 19:08:19--  http://github.com/
Resolving github.com (github.com)... 204.232.175.90
Connecting to github.com (github.com)|204.232.175.90|:80... connected.
HTTP request sent, awaiting response... 301 Moved Permanently
Location: https://github.com/ [following]
--2013-05-10 19:08:20--  https://github.com/
Connecting to github.com (github.com)|204.232.175.90|:443... connected.

The same commands works on the network node.

The pattern that I can see is that any SSL website fails (port 443) but then something like yahoo fails also and its at port 80.


Here are my security rules:
+-------------+-----------+---------+-----------+--------------+
| IP Protocol | From Port | To Port | IP Range  | Source Group |
+-------------+-----------+---------+-----------+--------------+
| icmp        | -1        | -1      | 0.0.0.0/0 |              |
| tcp         | 1         | 65535   | 0.0.0.0/0 |              |
| tcp         | 22        | 22      | 0.0.0.0/0 |              |
| tcp         | 80        | 80      | 0.0.0.0/0 |              |
| tcp         | 443       | 443     | 0.0.0.0/0 |              |
+-------------+-----------+---------+-----------+--------------+

I have messed around with all kinds of combinations of security rules but no luck so far.

Can anyone suggest how I can start debugging this.

Thanks,
