PAT not translating at all












3














I am studying for my CCENT.
I threw together a PAT practice lab.
Other than DHCP and RIP everything is pretty stock.
No VLANs
No security
Just NAT overload on ACCESS router.
I am stumped why it isn't translating
It will still ping all around.
show ip nat statistics, miss count is going up.
Debugging for NAT is on but silent.
It all looks like it should be working.



Is there something wrong with my configuration?

  • You really need to give us all the router configurations, and we need to know specifically what doesn't seem to be working. Also, if you are trying to run a routing protocol through NAPT, you must understand that is not going to work.

Looks like the NAT access-list 1 is too tight. host 10.0.0.0 will only match the single host with address 10.0.0.0, and you have no such host.



You almost certainly wanted this:



access-list 1 permit 10.0.0.0 0.0.0.255


which will include your hosts at the bottom of your diagram.

  • The back-tick is also sometimes called left-single-quote or grave (which I can't type here) en.wikipedia.org/wiki/Grave_accent#Use_in_programming You don't type the braces, you click on the braces icon, which isn't obvious to me either. Or you can type four spaces at the front of each line (and blank lines above and below) a block to mark it like the configs.
