I have just set up a cloud using cloudstack 3.0. I have installed its management server on system having IP address 10.129.34.15, which can be accessed in browser using following url: "http://10.129.34.15:8080/client"
Now I made an entry in DNS server as follows: 10.129.34.15:8080 maps to www.cse.iitb.ac.in/rcloud
So I can access the cloudstack interface in browser using: http://www.cse.iitb.ac.in/rcloud/client
Now when I use "http://www.cse.iitb.ac.in/rcloud/client" and I enter my username and password in the interface, then it says invalid username/password and does not allow me to login. But if I use "http://10.129.34.15:8080/client" while I am in same subnet, then it allows me to login and everything is fine there.
