NAT Overlap

Jul 07, 2006 0 Replies

Dear Friends,



I'm trying in a lab environment to allow access from a Network (10.x.x.x) to 2 other networks that has exactly the same subnet (example 20.20.20.0/24)



I reserved 2 other ranges be used as NAT. EX: 50.50.50.0/24 and



60.60.60.0/24

The problem is that, imagine that I have to connect into 2 server using the same IP address at (20.20.20.1). Until now, I tried using VRF, but even though when I input the same outside static nat line command I got the same error:



C3745(config)#ip nat outside source static 20.20.20.1 60.60.60.1 vrf vrf2 % 20.20.20.1 already mapped (50.50.50.1 -> 20.20.20.1)



The first one works fine: ip nat outside source static 20.20.20.1 50.50.50.1 vrf vrf1



My topoly is just like that



Net 10.x.xx.x------Router--------Link to 2 other Routers-------Net 20.x



Any idea?



Regards,



Leandro
