Hello group, I'm not getting the reason why this Basic Double NAT scenario doesn't work:
R1===R2===R3 R1: ! interface FastEthernet0/0 ip address 20.20.20.1 255.255.255.0 ! R2: ! interface FastEthernet0/0 ip address 20.20.20.2 255.255.255.0 ip nat outside ip virtual-reassembly ! interface FastEthernet0/1 ip address 10.10.10.2 255.255.255.0 ip nat inside ip virtual-reassembly ! ip nat inside source static 10.10.10.3 20.20.20.3 ip nat outside source static 20.20.20.1 10.10.10.1 ! R3: ! interface FastEthernet0/1 ip address 10.10.10.3 255.255.255.0 ! Traffic from R1 to R3 arrives to R3 and R3 sends back the traffic to R1 but for some reason R2 blocks this return traffic. Routers running 12.4.24T. Thanks.
