6.2 - EMS integration, unable to specify ip.

Hi,

I am trying to get the EMS connection from my Fortigate (6.2) working. But I am unable to set the source ip ? .. I have tried "unset source-ip" butstill no go.

I am also having a hard time understanding the pre-configured source ip in general..what is this ? 

In addition, do anyone know of anny commands I can run to verify that this works ? - I cant see anything in any logs ..nothing seems to happen... I'm a bit lost :)
