God dammit !

 

i explorted the tcpdump to wireshark.

 

and i did some testing and i noticed that when the packet exit one feed (CRS1) and return the other on (CRS2) i have this problem

 

i took one of the legs down > and its good.

 

 

I suspected in this first place, that why i enabled "mirror connection" on the virtuals and it didn't work.

 

 

So maybe i need some kind of persistence, but no such configuration on the Forwarding(IP).
