NAT for IPsec traffic through ISR

I have a IPsec tunnel between Site A and Site B. I have applied policy based routing to send all traffic of  192.16.10.100 to site B.

On site B, I want to use NAT to forward traffic of 192.168.10.100 received from tunnel to internet. 

Remaining all users of subnet 192.168.10.0 are using internet from site A where as only 192.168.10.100 has to go to SITE B via tunnel and then use internet of Site B.  The tunnel between SITE A and SITE B is established via tunnel.

 

 

SITE B

interface GigabitEthernet0/1/0
ip address 173.240.184.126 255.255.255.252
load-interval 30
negotiation auto
crypto map GCX_MAP
end

we need to know the following configuration what is the content of GCX_MAP

 

or use below example - split-tunnel (remove IP address from that list) so that will use full cone of IPSEC running for Corporate and Internet traffic, (make sure if you have a proxy in your environment, may have side effects)
