i have installed SFM, But after adding device my default static ip for the device is changing to default gateway ip.

I have installed SFM, i have static ip on my both the node

i am tring to add the branch office device in sfm with static ip which i use to access that device. 

i am able to add the device on first time. but some how the ip of device is getting changeing from static ip to a local ip. 

i dont know the besic setup for SFM. If basic need for statup with sfm can be define by some one it will be very help full.
