Ccr1036 routing helpp

I have ccr1036. I configure pppoe server for my costumers.
I have metro ethernet connection. I have a ip block. I use netmap function for my costumers to give ip address.

add action=netmap chain=dstnat comment=Static ip dst-address=xxx.xxx.xxx.xxx
in-interface=MetroEthernet to-addresses=yyy.yyy.yyy.yyy
add action=netmap chain=srcnat comment=Static ip out-interface=MetroEthernet
src-address=yyy.yyy.yyy.yyy to-addresses=xxx.xxx.xxx.xxx
With this command my costumer surf on the net with my xxx.xxx.xxx.xxx ip number and if want to connect his computer from other network it works.

But when the other my pppoe connection customer want to connect this ip (xxx.xxx.xxx.xxx) it isn’t connect. How can i correct this. I try a lot of nat rules but i cant correct.

is there anysolution for this please help
