Help with YCS Server connection


I want to connect to the Ysf side of the YCS Server. Works ok If I connect to the Fcs side
At the moment I have.
Ysfreflector to MB to MB to Ysfgateway to YCS (Ysf DG-ID 35)

Traffic passes from the Ycs side. But not from the Ysfreflector side. 

MB does not want to talk to Ysfgateway when set to connect to YSF
