<p dir="ltr">Sorry about the confusion!</p>
<p dir="ltr">I have two nodes, with two network interfaces each. One configured with 192.* IP and one with 133.*<br>
I can access them with SSH directly at 133.*</p>
<p dir="ltr">Both nodes can ping one another and both nodes can ping Internet addresses e.g. google. com </p>
<p dir="ltr">No other router available for configuration. <br>
No openstack yet.</p>
<p dir="ltr">So, my question is the following :</p>
<p dir="ltr">If I want to install openstack should I modify the external network interface so that it doesn't have an IP address? If I do that how can I access the server then?</p>
<p dir="ltr">I was under the impression that the document was talking about a situation like the above when it clearly doesn't. That's why I am looking for new guidelines. </p>
<p dir="ltr">All the best,</p>
<p dir="ltr">George</p>

Unfortunately in my setup there is no router for the management<br>
interface since it is much simpler and has two interfaces: one that has<br>
an external IP and connects directly to the internet and a second one<br>
with internal (management) network that cannot be reached from the<br>
outside. In such a case can you recommend a setup or point me at a<br>
documentation?<br>
<br>
Thanks a lot again,<br>
