Hello, I started thinking about this when doing task 34.2.7. The task asks "If addresses are exhausted, allow for PAT." I took this to mean "if dynamic 1 to 1 NAT IPs are exhausted, switch to PAT to continue to provide connectivity to source IPs". Apparently the DSG has a different interpretation, but it got me thinking of how to accomplish this either way.
On ASAs it's super easy to have dynamic 1 to 1 NAT happen, then PAT. You create a pool of many IP address, then you add to that pool a single IP address. The ASA assumes when you put in a single IP you want to overload, so it does 1 to 1 NAT for the first set of IPs in the pool, then uses NAT overload with the second set (1 IP) in the pool if the first set runs out. Is there any way to accomplish this on a router? I've googled around a bit but I seem to only come up with ways to do NAT overload to multihome to two ISPs.
