Cannot nat across Site to site VPN
I have network A as 10.201.10.0/23 and it is connected to network b 128.1.0.0/16 via site to site VPN on cisco 5505.
This is working as needed, but I need just one host on network A to be natted from 10.201.10.6 to 128.1.1.5 when it reaches network B.
Here is a jpg of the configuration and the configs for both router A and router.
Here are the configs....

So, first, is it as simple as a typo of 10.201.10.x versus 10.206.10.x? Make sure you know how it's supposed to be.
If that's not it, though, does the network at the other end know where the address used in your "global (outside)" statement is located? Your ACL of what gets encrypted specifies the inside address, so chances are their ACL at the other end specifies the reverse of yours -- but doesn't in any way mention the 128.1.1.x subnet.
I haven't played with this kind of NAT situation too much, but my guess is your ACL should probably specify 128.1.1.x as the source subnet, and you probably need to modify your NAT criteria to base it off an ACL that specifies traffic specifically destined for 128.1.0.11.
See if the first suggestion works and lets go from there.

You need to reconfigure some things to setup policy NAT.

! The above will cause only the traffic coming from 10.201.10.6 to 128.1.0.0/16 to be NATed. The rest will flow non-nated.
access-list 100 permit ip host 128.1.1.5 128.1.0.0 255.255.0.0
! This causes the NATed traffic to be sent through the Tunnel.
On Network B ASA:
access-list 100 permit ip 128.1.0.0 255.255.0.0 host 128.1.1.5
route outside 128.1.1.5 255.255.255.0 192.168.2.2
! This routes the traffic back through the VPN tunnel for the NATed traffic.
I keep getting this

I dont think we need to use policy nating for the traffic you dont want to nat. That traffic should be in the nonat ACL and the nat (inside) 0 command.

That should cause the traffic to be NATed the way we want. Check the tunnel to see if theres any traffic being sent /received. Use 'show crypto ipsec'

Where are you originating the Ping from? The ASA itself or from a device on the inside interface of Site A's firewall or Site B's firewall? Is the traffic actually going through the VPN?
I have a laptop on each side and a router on each side .....so to answer the ? I am originating from laptop 128.1.70.107 to laptop 10.201.10.6...traffic is passing because I can ping from laptop 128.1.70.107 to the router on the other side 10.201.10.1
I'll try to lab it up and test the configs. I'm pretty sure what I've tried to do should work, there maybe a detail I'm missing though.
I got it working. There is an issue with doing it the way you've setup though. The problem is that even if you setup everything perfectly, the traffic will not route back correctly from the 128.1.0.11 device without a static route on that device specifically for the 128.1.1.5 IP. 128.1.1.5 is in the same network as 128.1.0.11 so the traffic never gets routed back to the ASA to go through the VPN tunnel. So in addition to the below configurations I had to add a route on my 128.1.0.11 device like:
ip route 128.1.1.5 255.255.255.255 128.1.70.100
(I was using a router)
Once I did that I was able to ping through from 10.201.10.6, get natted to 128.1.1.5, go through the VPN, then come all the way back.... Using the below configurations.
ip route 128.1.1.5 255.255.255.255 128.1.70.100
(I was using a router)
Once I did that I was able to ping through from 10.201.10.6, get natted to 128.1.1.5, go through the VPN, then come all the way back.... Using the below configurations.

OK Gavving,
I put in the configs. I put in the static routes on all routers involved (3 of them, one for each site and one for the site to site VPN)
Now I can ping my routers on each side.
I can ping from my Site A router to a host on Site B and vice versa. (E.G. from 10.201.10.1 to 128.1.70.107)
I can ping from my router on Site B to the router on Site A and to 128.1.1.5
Sending 5, 100-byte ICMP Echos to 128.1.1.5, timeout is 2 seconds:
!!!!!
Success rate is 100 percent
I can ping from 10.201.10.6 to the router in Site B (10.201.10.6 to 128.1.250.0)
I cannot ping from 10.201.10.6 to a host in Site B (10.201.10.6 to 128.1.70.107) see below from the logs...Both ASA's thinks it happens, but the request times out on the host...

Log entry from Site A ASA:
CPF(config)# %ASA-6-302020: Built outbound ICMP connection for faddr 128.1.70.10
7/0 gaddr 128.1.1.5/512 laddr 10.201.10.6/512

/512 laddr 10.201.10.6/512
Then pinging 10.201.10.6 OR 128.1.1.5 from host in site B 128.1.70.107 the ping also times out....
Here is the log entry from Site B asa
MDV(config)# %ASA-6-302020: Built outbound ICMP connection for faddr 10.201.10.6

Log entry from Site A ASA for same ping...

Do you need to see anymore to see if this works?
On host in site B, IP: 128.1.70.107 what is the routing table? Did you specifically add a route for 128.1.1.5/32 like I mentioned in my previous post? You will have to do that for it to work because we are NATing into the same network block as the host's interface IP. If you were to look at the traffic counters on the 'show crypto ipsec' output you would see packets being sent from Site A, received on site B, but nothing coming back. This is because the traffic never hits the ASA on the site B end as the host will ARP and look for 128.1.1.5 on the local LAN.
I just thought of something though. If we enable proxy arp on the inside interface, we wouldnt need to add that route. Try:
no sysopt noproxyarp inside
on the Site B ASA.
