Topology we will be using is similar to the ones from my previous posts on this series.
Should be a breeze to configure the interfaces with IP and description etc or you can look at my previous NAT posts.
Relevant configurations regarding the NAT statements are posted below.
- Define the NAT 'inside' interface. See previous posts if you need a refresher but basically 'ip nat inside' on R2 fast1/0.
- Define the NAT 'outside' interface. See previous NAT posts if you need a refresher but basically 'ip nat outside' on R2 fast1/1.
- Create an access-list to match the subnet(s) to be NAT'd.
- Create the NAT statement.
Show commands to verify:
Notice that I initiated two telnet sessions from R4, each with a different source port and you can see the associated two different matching entries in the NAT translation table.
- Make sure to have 'ip nat inside' and 'ip nat outside' under the correct interface.
- Make sure you are seeing hits.
- Make sure you have the correct 'ip nat inside source' statement with the correct access-list.
