How to use fog Server in different Network?

[Esmael Kedir]

the Description of my question is listed below:
[LIST]
[]I installed fog server in my Laptop on Ubuntu 12.10 with the following setting and environment
[]IP address: default:10.140.252.214 which is provided by our DHCP Server in the Organization
[]DHCP Server: Fog itself
[]DNS:default Network Range in my Office: 10.140.252.0-10.140.252.255
[/LIST]
Note: I can’t to use our organization DHCP server to set the fog server port addresses.

:)After this everything is ok. I can open the fog page: 10.140.252.214/fog/management I can register host and can see in the Fog Server

But the Problem I faced is:
[LIST]
[]I changed my office with the 10.140.190.0-10.140.190.255 Ip range
[]ip Address is one of from the above range.
[/LIST]
Now i can’t to use the previous 140.252.214/fog/management fog server Page.
And i can’t to boot from pxe and nothing fog Logo apears
So How can i open and use fog Server page with the new ip e.g. 10.140.190.82/fog/managment?
