Help with VRF aware NAT setup

[pangassam]

Hello dear friends,

I am seeking your help for the setup of NAT on Cisco 3945 platform. The diagram and configuration of the NAT router in my scenario is in attachment.

Here is the scenario: I have two hosts Host-A and B with identical IP address (10.255.255.210) going to same router (Cisco-B), they both try to access to the same resource 192.168.10.10. I've defined two VRFs, A and B on Cisco-B where the two hosts are attached to, Cisco-A has no VRF, it's a router managed by my ISP. 

With the provided configuration, there is no NAT translation on Cisco-B and of course, no host can ping 192.168.10.10. I've changed my configuration to use NVI but I am stuck with the same result.

Could you please tell me what I am missing?

1) ip nat inside source static 10.225.255.250 10.238.17.69 vrf VRF-A >>>>> Host has IP address 10.225.255.210 and you have configured NAT for 10.225.255.250 so you need to changed it.

2) interface GigabitEthernet0/1.28 and GigabitEthernet0/0.18 do not have ip vrf forwarding VRF-B

Kindly rate for useful post

Thank you Pawan,

Actually I've removed the VRF under  interface GigabitEthernet0/1.28 and GigabitEthernet0/0.18 for testing purposes. I've fixed the NAT statement, I still don't see any translation for the IP 10.255.255.210.

I think I found a work around, I have to add a host route on Cisco-A for each NATed address, I realized it doesn't have ARP entries for them. Any better option ?
