I configured NAT on a cisco 2811 router running but it's not working. Following are the commands:
interface FastEthernet0/0
ip address 192.168.1.7 255.255.255.0
ip nat inside
ip virtual-reassembly
duplex auto
speed auto
!
interface FastEthernet0/1
ip address 172.16.20.106 255.255.255.252
ip nat outside
ip virtual-reassembly
duplex auto
speed auto
!
ip classless
ip route 0.0.0.0 0.0.0.0 172.16.20.105
ip route 10.2.8.0 255.255.248.0 172.16.20.105
!
ip http server
no ip http secure-server
ip nat source static 192.168.1.112 10.234.8.2
!
I try to ping 10.2.8.15 from a Laptop (192.168.1.112) connected to the NAT inside interface but ping is unsuccesful and when i do a show ip nat translation i see nothing. I've erased the nvram and reconfigured same nat commands without success. I've also tried dynamic nat using "ip nat source list pool" command without success. I'm surprised. The ios image is (C2800NM-ADVSECURITYK9-M), Version 12.4(3i). Please assist. Thanks.

Configure:
no ip nat source static 192.168.1.112 10.234.8.2
ip nat inside source static 192.168.1.112 10.234.8.2
or pool dynamic, or interface.

Thanks so much. Spent hours wondering why where it's just due to my skipping the inside keyword. But then, I wonder, how come the router took the command?
Thanks anyway.

Because it does something else, that is not of much use anyway.
Thanks for the nice rating and good luck!

If you don't mind explaining, I'd like to know the something else that it does. I ran debugs then but didn't see anything.
