NAT Destination Server Based On Source Address

[Feblex123]

We would like to know if we can achieve the following scenario with NAT configurations on our Cisco Routers:

Based on the diagram above, we would like that:

1- When Host A  (1.1.1.1) connects to the public IP address 3.3.3.3 over the internet, 3.3.3.3 translates to Server A (192.168.1.1).

2- When Host B  (2.2.2.2) connects to the public IP address 3.3.3.3 over the internet, 3.3.3.3 translates to Server B (192.168.1.2).

3- When either Server A or Server B tries to access the internet, they can both be translated to 3.3.3.3.

You NAT with route-map match acl 

From client to server set interface as ISP 1 or ISP2.

Hello

You don’t state what service you need to connect via to those servers?

Static port address translation is a possible solution 

example:

ip nat inside source static tcp 192.168.1.1 80 3,3,3,3 80 

ip nat inside source static tcp 192.168.1.2 443 3,3,3,3 443

Hello,

I am not sure understand your topology to be honest. What is the full path the hosts take towards the servers ? What is 3.3.3.3, is that an IP address you control ? Change your diagram so it shows all individual hops between the hosts and the servers...
