Please see attached topology.
I have two servers that I have no control over - only where they plug into my NK9 switches.
They both have the same ip address/gateway and they need to be reachable by two other servers.
How would you go about solving this?
I was thinking I could use ip nat outside rules with a unique outside local IP that points to each server using vrf aware NAT.
Any other suggestions?
in that case you are in right direction NAT VRF aware for the overlap address.
here is example guide : ( make sure check the Limitation before deploying) section VRF Aware NAT (NOTE)
From the provided link:
The VRF aware NAT feature is not supported on the Cisco Nexus 9300-EX, 9300-FX, 9300-FX2 and 9300-GX platform switches.
I am running a 9318-FX - I assume the 9300-FX means the whole 93xx-FX product line?
