[ubuntu] ubuntu cloud infrastructure setup problem

Hi,

I am configuring the Ubuntu cloud infrastructure 12.04 LTS.
I sucessfully configured the MASS server with extra virtual ip.
Mass Server : eth0 => 192.168.10.171
eth0:0 => 192.168.10.172

Now, i install JUJU in the same server and configure the two nodes using Mac address. As per the documentation i configure two nodes on DHCP server.
Network Range : 192.168.10.171,192.168.10.178
Node1 => 192.168.10.174
Node2 => 192.168.10.178

after juju bootstrap these two nodes showing status ready and i can boot then by click on MASS server URL account.

Now, i am deploying the mysql & wordpress using JUJU its sucessfully configured but "JUJU status" command not showing the URL from which i can access it.
As per docs node1 is configured for mysql and node2 is configured for wordpress.

Output :
mass@mass:~$ juju status
