L2L Tunnel and NAT question

I need a little help. I am trying to setup a l2l tunnel on ASA 9.9.2 between 4 specific hosts on my side to 4 specific hosts on the peer-side. The problem that I can’t seem to wrap my head around is hosts on my side need to nat to a specific subnet before entering the tunnel.

​

Example Setup – (IPs have been changed to protect the innocent)

​

Hosts on my side of tunnel are – 10.1.1.1/24, 10.1.1.2/24 and 77.34.76.1/23, 77.34.77.1/23

​

These hosts need to nat to 192.168.10.1/24.

​

Basically we have overlapping networks on my side of the tunnel, but not for the hosts on the peer-side of the tunnel.

​

Any ideas or thoughts would greatly be appreciated. Thanks in advance for the help!
