Remember, ACLs on the ASA allow you to override the default security behavior which is as follows: Traffic that goes from a lower security interface is denied when it goes to ciscoasa(config)# object network IPv4_POOL ciscoasa(config-network-object)# range 203.0.113.1 203.0.113.254 Step 4 Configure PAT for the inside IPv6 network. Network object groups are particularly useful for creating a mapped address pool with discontinous IP address ranges or multiple hosts or subnets.

Not the answer you're looking for? Nat (inside Outside) Source Static Anyway, I'll spare you the endless futile attempts to figure out what eventually worked... To use multi-session PAT for traffic, you can configure per-session PAT rules: a permit rule uses per-session PAT, and a deny rule uses multi-session PAT. Typically, you configure the same number of mapped addresses as real addresses for a one-to-one mapping.
