Cisco – How to start Cisco 2911 with presaved configuration

To get a better picture of what happens, you can do a show file systems | i flash|nvram, dir nvram:, and dir flash: on some of the devices in question. The short answer: NVRAM is a kind of flash memory, and it is never removable. The location of vlan.dat varies by switching platform... the IOS configfiles are always in nvram unless the device is forced to manually store them elsewhere.

Can you show output of 'sh ip nat stat' and 'sh ip nat tran'?

I think the config looks correct, did you try applying an ACL on the outside interface to specifically allow the traffic?

interface GigabitEthernet0/0
 ip access-group OUTBOUND out
!
ip access-list extended OUTBOUND
 permit ip any any

here's a working example from a 1800 series:

interface FastEthernet0
 description $FW_OUTSIDE$
 bandwidth 34000
 ip address 1.2.3.141 255.255.255.240
 ip access-group OUTBOUND out
 ip verify unicast reverse-path
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip nat outside
 ip virtual-reassembly
 load-interval 60
 duplex auto
 speed auto
!
interface FastEthernet1
 description $FW_INSIDE$
 bandwidth 34000
 ip address 192.168.0.254 255.255.255.0
 no ip redirects
 no ip unreachables
 no ip proxy-arp
 ip nat inside
 ip virtual-reassembly
 load-interval 60
 duplex auto
 speed auto
!
ip nat pool GLOBAL_IP_POOL 1.2.3.139 1.2.3.141 prefix-length 24
ip nat inside source route-map natmap pool GLOBAL_IP_POOL overload
!
ip access-list extended natrules
 deny   ip 192.168.0.0 0.0.0.255 10.180.3.0 0.0.0.255
 permit ip 192.168.0.0 0.0.255.255 any
!
route-map natmap permit 10
 match ip address natrules

Hope this helps.

Edited:

I cannot spot anything weird with your config. Since you seem not to have any hits in translation tables at all, there must be a problem either on the connectivity or configuration on the client, or simply an access-list that denies the traffic.

Can you:

1) ping from the router, make sure you do it from the correct interface by entering:

ping 8.8.8.8 source 10.1.1.1

2) show access-lists

show access-lists

I set up three routers in a lab and configured rip + nat, and it works just as it is. The router in question and the remote router that specifically denies the internal network of 'the router in question'.
