 You could also use the web interface to access the console, but that's not quite the same.
 As before, in the Network Gear section, get a campus IP address from our pool.
-<code>$ openstack floating ip create</code>
+<code>openstack floating ip create
+openstack server add floating ip myserver 128.135.37.XX
+</code>
+Note that the command is showing you a deeper and more rare UX pattern than before:
+<code>
+openstack server $action $subresource $more_options
+</code>
 At last, you can ssh into 128.135.37.XX. It is important for you to realize that your __local__ server IP does not change (no new interface is given to the instance). Instead, the router on the subnet simply performs DNAT on behalf of the clients. Here's another possibility:
 <code>$ openstack server add network myserver campus37</code>
-**Now** your server does have a new interface attached to it, and will be served a DHCP address there. You will almost certainly have to inform the OS about this, and the cloud tools won't help you with that...
+**Now** your server does have a **new** network interface attached to it, and will be served a DHCP address on it. You will almost certainly have to inform the OS about this manually; the cloud may not help you do that.
+This section added a floating ip address directly to the server. You must realize that a router was needed on the subnet for that to happen. We had created the router earlier for the purpose of SNAT, and had we not done that, this command would have failed. This means that if you are not doing SNAT, you should create a router anyway, but __do not__ give it a campus address of its own.
