Command "Show ip nat translations" doesnt output anything

[Rui Fernandes]

I already tried 2 different ways (2 pictures attached) of configure IP Dynamic NAT and both still doesn't output anything. I saw other posts and I already tried to change the mask to 0.255.255.255 but it still doesn't working. Someone can help?

Hello
sh ip arp
sh ip route

Would you post the output of show arp? Are you sure that there are devices connected in the 2 inside subnets and that some of them have attempted to access something outside?

[Rui Fernandes]

In the images below you can see the "show arp" output and the network architecture.

Thanks for the additional information. The ip route information verifies that there is a default route with fa5/0 as the outbound interface. The arp output does verify that there is a connected device on fa5/0 which is configured as nat outside, and there is a connected device on fa4/0 which should still be configured as nat inside. Assuming that the config has not changed it should be correct and with connected devices. So the remaining question is whether you can verify that the host connected on fa4/0 has actually attempted to access something outside.

After run the commands,

int fa4/0

ip nat inside

there is a print of simulation of 3 different PCS connecting to ISP router.

In your bug_2 output your syntax is not correct. In your translation statement you have the work list but not the list number. I am a bit surprised that this did not generate some syntax error when you entered it, but I believe that this is the reason there is no output.

In your second set of output we do not see any interfaces that have addresses in the 10.0.0 address space. Are there interfaces in that range? If so what are they? This could be the reason for no output here.

[Rui Fernandes]

Thanks for trying to help, I noticed the error in the access list but even correcting I have no output.

I don't understand the second point. I intend to connect 3 LANS to a router that connects to a public router. You can see the connection diagram in the figure below (ex.png) where the routers are already configured with IP routing table.

Hello

Okay so your config look good -apart from the mis-type with you acl you could try the following:

no ip nat inside source list pool POOL overload 

ip nat inside source-list 1 interface fa0/5

Hello,

post the full running configuration (sh run), maybe we can spot something else that causes the router to not translate anything...

[paul driver]

Hello

The Nat configuration on your wan rtr at this time looks okay and you have active hosts however between the lan hosts and this nat wan rtr are two other rtrs and its possible the routing in-between is incomplete.

From a lan host can you traceroute towards 193.177.68.2
Also post the again these commands from those rtrs also and attach the output to a file in your OP

sh ip arp
sh ip route
sh run

I can communicate between PC on a LAN to the ISP via the ICMP protocol, i showed it replying to other person in this discussion (image sim.png). I attached the .rpa file to make it easier to analyze, if you can!
